Wall Bangers: Star Trek: Voyager

    open/close all folders 

    Threshold 
It's not a character or plot arc, but a single episode. Yes, one episode is so bad, it has its own folder within a show subpage.

  • Voyager, infamous for the quality of its writing or lack thereof, managed to have one episode so bad that the powers that be noticed: "Threshold". In it, the characters, while attempting to figure out a way to get back to the Alpha Quadrant, break a law of series physics and two "evolve" into newts as a result. Then they make out and have baby newts, which is why Agony Booth winced. Both fans and writers pretend that episode never happened.
  • This episode also occurred before Voyager found a way to communicate with the Federation. All Janeway had to do was put one volunteer on the transwarp shuttle with the Doctor's newt-mutation-curing hypospray and send them back to Starfleet HQ to tell them what was going on. Instead, the whole transwarp shuttle was ditched and never spoken of again. Or scale the transwarp drive up, and send the whole damn ship back to Earth with the Doctor in command (so he can administer the hypospray antidote upon arrival, or at least instruct others to do so). Problem solved!
  • Even if it wasn't possible to create a man-portable version of the cure (it is, but bear with us) the Doctor, with limited research on the subject and comparatively limited tools, took no more than a day to cure it. Starfleet Medical, with state of the art equipment, the brightest doctors in the Quadrant, their own EMH programmes and full access to the Doctor's research should have been able to cure the mutation both independently and on a completely superior time scale.
  • There was nothing stopping the crew from wiring the engine into their ship, accelerating to Warp 9.9997283-whatever, getting home in about a week, and not having to worry about mutations at all. It also doesn't help that this episode forgets the rules that govern how warp drive works. For the record, going to Warp 10 after changing the dilithium is roughly equivalent to flying a nuclear submarine to the Moon after throwing in some new Phlebotinum control rods.
  • Why is a small ship like Voyager, with a limited staff of non-specialists, able to make a breakthrough that nobody in the Alpha Quadrant could. Also, since communications move much faster than the vessels themselves, why isn't Starfleet's every data transmission receiveable at every point in the universe? Even with the conceit that they were the only ones to have "super-dilithium", it's completely absurd to equip a shuttle designed to handle no more than warp 4 (slower than the NX-01 remember) with the ability to travel at the speed of infinity. The assumed scenario is that it would rip apart long before then. This has even been shown in every single episode previously when a starship reaches maximum speed - the warp core begins to light up like a Christmas tree.
    • This was actually shown to be a problem in the simulations Paris, Torris and Kim run before the experiment (the shuttle was ripped apart in the opening scene), and they talk about making several modifications to the shuttle to compensate. What those modifications are never are explained and the shuttle doesn't look any different.
  • The shuttlecraft environment is already optimized for humanoid lifeforms. Why would accelerated evolution in that same environment result in newt-like creatures who are de-adapted from their surroundings? Even by the standards of Star Trek in general, this episode pretty clearly proved that few, if any, people involved actually understood what evolution is. Not only is evolution not something that happens to a single individual, evolution occurs over many generations. Even among some kinds of insects that evolve in a relatively quick manner you aren't going to see this.
  • One of the most outrageous claims is when Tom and Belanna claim they are trying to break the Warp 10 barrier. Warp 10 is infinite speed. There's no threshold to cross because infinity is a mathematical concept, not a real number. That's really not an esoteric bit of information — most juniors in high school could probably tell you that — so one really has to wonder the mistakes in this episode were just a case of something really obvious slipping through the production process, or the production staff was just that contemptuous of the audience's intelligence.

    General 
  • Almost every time Janeway talks about the Prime Directive or Starfleet protocols. One week, she's willing to kill the entire crew to stick to them; the next week, she's willing to kill the crew to violate them, though those weeks she won't admit that's what she's doing. It's more than halfway through the series (at the episode "Equinox") before she even admits to even breaking it once! No wonder The Doctor kept a log of all her questionable command decisions. It's clear that nobody at Paramount seemed to be able to agree on what the Prime Directive actually means. Half the time, they do apply it to warp-capable races. This is one of the reasons SF Debris is convinced Janeway is a schizophrenic.
  • The constant search for deuterium in the first few seasons. Deuterium is an isotope of hydrogen and one of the most common isotopes in the universe. There are over 10,000,000,000,000,000 metric tons of deuterium just in Earth's oceans alone. Even worse, the official writer's bible and supplemental materials mention that the ship has a Bussard/Brussard Ram Scoop that collects floating hydrogen isotopes (in short, travelling through space will net you hydrogen and deuterium). How many planets with oceans did Voyager sail past in those seasons? How many trillion tons of water floating around in space as ice, a la Saturn's rings or comets? They even acknowledged it in a later episode by having Tom Paris say something along the lines of "Why steal deuterium? You can find it everywhere."
  • Set course for the Alpha Quadrant! Apparently both the script writers, Starfleet and Voyager's navigational staff forgot that the Beta Quadrant's boundary passes right alongside Earth's Solar system. This means that, according the the canonical map, the quickest route from the Caretaker Array to Earth is Delta - Beta - Alpha. In order to traverse Delta to Alpha, it would require going through the centre of the Galaxy which is an increase of many thousands of light years. There are unfortunately tales that the production staff thought that fans would find the concept of ''three'' quadrants far too confusing. A graphic of Voyager's flight path reveals that it passes through the Beta Quadrant for most of the second half of their journey, distance-wise. Voyager was in fact near the boundary of the Beta quadrant in "Endgame".
  • Vidiians. Oh, Vidiians. You're a warp capable species with advanced medical technology and the ability to split B'Elanna Torres into a full (but dying) human and a living (but barely sentient) full Klingon. So... the Delta Quadrant, especially the piece of it the Vidiians are in, is at the ass-end of space, with plenty of dumb, defenceless races. And you need to harvest organs to sustain yourself against the ravages of the Phage... so, who do you go after to get those tasty organs? One advanced starship with about a hundred people on it - when there are planets full of people who haven't even achieved space flight or who are pacifists! You should be setting up shop there, doing some abductions, and then you're set. You don't even need to chase anyone ... but no, you go after Voyager. The only reason for this would be that Klingons seem to have some natural immunity to the Phage; but in that case, as B'Elanna could be the cure, why not just get a fleet together and go after what is possibly the most important thing to the survival of your species, instead of half-assing it a few times? (She's the only Klingon in the Delta Quadrant, after all...)
    • For that matter, why harvest internal organs from sentient races at all? Just find an agricultural planet with biochemically-compatible livestock, and offer to haul off a few hundred tons of fresh offal from the local slaughterhouses every week.
    • If the Vidiians are so advanced, then why don't they just go to Janeway, ask for a pint of blood and some stem cells, and manufacture the needed organs and antibodies themselves? The Doctor did this in another episode when he manufactured antibodies from B'Elanna's baby to cure a Klingon plague. Then again, knowing the writing on Voyager, this would be the time when Janeway would stand up and insist that giving the Vidiians even one dead skin cell of any crew member would be violating the Prime Directive and upsetting the balance of power in the Delta Quadrant.
    • It gets worse: "Lifesigns" indicates that there are some Vidiians that aren't infected with the Phage... But the Vidiian doctor who is the guest star of that episode and who is clearly infected was sent to treat an outbreak in one such colony. As SF Debris pointed out, haven't these people heard of quarantine?
    • It could have been simple. The Vidiians are warp-capable; the Prime Directive doesn't apply to them. Voyager's medical database probably contains complete information about all Alpha Quadrant sentients, including Klingons. Send the Vidiians the relevant information, and they can work out a cure for themselves. In return, Voyager gains a desperately needed ally with real power in the Delta Quadrant!
  • Voyager is a small ship, far from home, understaffed (yet with a fair supply of redshirts to throw into the grinder), and often low on resources. Over the course of the entire series, the grand number of pregnancies/possible pregnancies totals three, one of which happened before Voyager ever got stranded and another which the character in question, Kes, decided not to go through with (it's her species equivalent of pon-farr except with actual breeding instead of just sex). Yet, on a ship with limited resources even for its lacking crew, it's never discussed if this might affect the rest of the ship, especially in the early seasons when they actually pretended to care about that. Furthermore, it is actually mentioned "Elogium" (the above-mentioned Kes issue) that onboard fraternization among unnamed crew members (as well as Neelix and Kes) was already occurring. Kes could have become a mom then if that fertility period was real (which we'll never know). If this is true, the idea that they could go seven years and only once have to deal with a pregnancy, one that was the intent of said couple at that, is rather hard to accept.

    Season 1 
  • Caretaker (Season 1, Episode 1 & 2):
    • An enemy ship disappears in what is one of the most dangerous regions in space. They couldn't have been destroyed; there'd be evidence of that, like wreckage. What does Voyager do? They fly through the same super-dangerous plasma-storm (even though they know the Maquis aren't in the plasma storm anymore). Why? You have faster than light engines — you can fly around it! (Then again, their flying through is required by the Anthropic Principle.)
    • Starfleet hires the guy who was with them for less than a single mission. For some reason, Starfleet assumes that he can now delve into the mind of all the Maquis and know where they headed. And why did they need someone who had experience with the Maquis to tell them that they would most likely be heading to a place where they can live? There was nothing stopping the Voyager crew from hiring a former Bajoran Resistance fighter who knew the Badlands just as well when they stopped for a layover at DS9.
    • A spacefaring race of desert dwellers are introduced who use water as currency because it is so scarce. On planets with oxygen-rich atmospheres. While powering their spacecraft with fusion reactors that run on hydrogen. This was lampshaded later by Seven of Nine, who deemed that they were "unfit for assimilation". Ouch.
    • The way Janeway handled the situation with the Caretaker. Although it has been (rightly) pointed out multiple times by commentators that Janeway couldn't just use the station to get back home because the Kazon were attacking, and the station would take several hours to charge up the machine that could beam them back home (and that was before a Kazon ship crashed into it), the writers apparently forgot that they undercut their moral dilemma in the first place and treated the situation as if Janeway had a choice between destroying the relay / saving the Ocampa or getting her crew home. The Array would realistically have been a lost cause. What they should have done was follow up on the things that were within her power, like potentially abandoning her mission and some of her crew to get the Caretaker to send her home before he died, or when a Kazon ship crashed into the Array, thus disabling the self-destruct and who knows what else, consider negotiating with the Kazon.
  • Time and Again (Season 1, Episode 3):
    • Why did Paris and Janeway join the fighting outside the power plant? They have never even heard of the government of the planet, they are trying to stay as anonymous as possible, and they are afraid of altering the timeline. Yet the second they see a police holding off a riot, with the police remaining calm and trying to avoid harming civilians, they jump in and start punching them.
    • Their questionable decisions are much worse than that. The two of them know that the civilization is about to be wiped out by their own energy source, but deliberately make no effort to warn anyone of the impending global massacre. At least Paris wants to warn them. Janeway just holds to her holy 'Prime Directive' even in an instance where no matter what their interference does it could not possibly be worse than the destruction of all life on the planet. This character is so obsessed with the Prime Directive that she is fully willing to watch all life on the planet be wiped out. How exactly did she make Vice Admiral again?
  • The Cloud (Season 1, Episode 6):
    • The ship is running low on power. Why, then, are they still using holodeck programs? Even worse, the attempted answer later on in the series is a Voodoo Shark (and the Trope Codifier for it) — it's explained at some point that Voyager's holodecks have an entirely separate power source that can't be tied into other systems on the ship.
    • Janeway refuses to let two un-enlisted people off the ship before flying into the belly of a space monster. What would be wrong about letting nonessential personnel off-board before committing a mission that could result in death if it doesn't increase the risk for anyone? Even with the later handwave that allowing people off the ship sets a precedent for crewmen to go off anytime they wanted a break, forcing everyone to stay on the ship in a dangerous situation makes Janeway sound like a lunatic. They aren't even her crew, for God's sake!

    Season 2 
  • The 37's (Season 2, Episode 1): The infamous Physics-defying pickup truck. The Voyager crew comes across a 1936 pickup truck just floating through outer space. They beam it aboard and discover that:
    1. There's still oil in the crankcase, water in the battery & radiator, and gas in the tank.
    2. It starts right up as soon as someone turns the key in the ignition. There's still electricity in the battery. Sealed batteries don't last much longer than a few years if they go unused.
    3. The lousy AM radio picks up a distress signal through atmospheric interference that none of Voyager's sophisticated communication equipment can pierce.
    4. It starts right up, despite the fact that it's a Ford.
    5. Torres can't identify cow manure even with a tricorder. Have cattle gone extinct in the Federation?
    • As if that weren't bad enough, it turns out that the owner of this brand-spanking-new truck was a poor black sharecropper who (along with a bunch of other people) was abducted from Earth... in 1937. Think about it. That was an age when rural areas still used mules.
  • Tattoo (Season 2, Episode 9):
    • Chakotay's Native American heritage is rubbed in, making it deeply racist. It was skewered rather marvelously by SF Debris (link) by transferring the plot to a Deep Space Nine episode about Sisko, with the aliens helping black culture. It ends with "Offended yet?"
    • Chakotay is a descendant of a South American Indian tribe who relocated en masse to a planet which, as of the start of Voyager, is in Cardassian space. He had set his cultural heritage aside before entering Starfleet and before entering the Maquis, but he owns and carries a medicine wheel anyway. In this episode, he is brought back to the religion of his people by the deities of that religion and goes on a vision quest. His religion is treated as real and true - only people of his heritage can fully subscribe to it, but it has power behind it. Even the Bajoran Prophets were shown to be Sufficiently Advanced Aliens before they were treated as gods; there is no such unmasking here. And his doing this quest is plot-critical — it's this or coma, pretty much.
    • It says his ancestors had no culture until the aliens gave it to them. Human beings create culture by virtue of being human beings — we couldn't stop doing it if we wanted to. But, for these people to have a complex and true religion, it has to have come from aliens?! And why is no one on the ship even tempted to go after these beings for what they did to these people? If the Q had tried that on a civilization and gotten caught, then there would be hell to pay...
    • The Sky Spirits are hypocrites on a hilariously large scale. In one of Chakotay's flashbacks we learn that they carve a healing symbol into the ground every time they chop down a tree or light a fire in order to apologize to nature for desecrating it. In the present, however, the Sky Spirits proceed to attack Voyager with a synthetic cyclone so large and powerful that it destroys and uproots a whole section of forest — which kind of puts a piddling little campfire to shame. And that's before you start to wonder just how much forest they would have to remove in order to construct the unseen power station and emitter large enough to weaponize the weather. Their love for the land also doesn't stretch to the actual animals living on said land, as they have a trained/mind-controlled hawk that tries to claw out your eyes.

    Season 3 
  • Remember (Season 3, Episode 6). Torres is the recipient of a telepathic message from a member of a group of guests on the ship, who claims that their species was the perpetrator of a massive genocide against members who were considered a lower class than them. Upon receiving the full message, Torres is incensed, and bursts into a congregation of these people in the ship's mess hall, accusing them of said genocide, followed up by a cover up. Although the story Torres received was plausible and believable, she has no tangible proof that any of this happened, and doesn't know if the woman who sent the message was a complete kook. Memory Alpha states that this story was meant to be a parable for the Holocaust, however it fails in this capacity for a number of reasons, not the least of which is the setting: an isolated ship far removed from the events of the alleged slaughter in both space and time. This is hardly Germany, Armenia, or Rwanda, where the murder was happening in front of various governments, multiple news sources and survivors were revealing the truth, and people just didn't listen. This is deep space, light years and decades from the alleged events, with only the word of one solitary person who, honestly, may be her world's version of a Moon landing conspiracy theorist, as any indication that anything happened at all. This doesn't prevent her story from being true, but one would think that given the complete lack of physical, tangible evidence that anything happened at all, Torres would be a bit hesitant to burst into a congregation of these people and call their entire species murderers. Being that she's part Klingon, she should know personally that bloody wars have started over far less in the ST universe (Real Life as well, but that is another topic).
  • Future's End (Season 3, Episode 8 & 9). The entire chain of events that starts the episode. Captain Braxton goes through time and attempts to destroy Voyager based solely on circumstantial evidence that wreckage from their ship was found in a temporal explosion. Instead of explaining the situation to them and asking what happened (after all, he's in a timeship and has a theoretically limitless amount of time to discuss this problem), he simply shoots right off the bat, and it's only when they stop him that he calmly explains the situation... before saying that he has "no time to explain" and absurdly expects that the crew will allow him to destroy them. No rationale is ever given for Braxton's bizarre behavior, even when they find him living on Earth or when the timeline repairs itself.
  • Warlord (Season 3, Episode 10). Kes' body is taken over by an enemy dictator, who then proceeds to break up with Neelix. Given how it is outright shown that it wasn't Kes, you would imagine that when she reclaimed her body their relationship would resume like nothing had happened... right? Instead, in every single episode afterward, not only is the body swap never referred to again, but it's outright stated in "Darkling" that it was Kes that broke up with Neelix — and not her captor. This implies one of two things: that Kes is such a coward or that Neelix is such a manipulator that she used it as an excuse, or that the script writers completely forgot about the events of this episode. Even worse, there was a scene from a later episode where they formally broke it off, but it wound up on the cutting room floor, leaving the matter officially unresolved.
  • Before and After (Season 3, Episode 21):
    • The episode involves a future (and elderly) version of Kes rewinding through her life to give her past self (the one from the current timeline) forewarning about various events over the next few years. The moment that Future Kes agonizes over the most is her marriage to Tom Paris and their child together — which, unbelievably, grows up in the span of less than nine years (the standard Ocampan lifespan), and marries Harry, Tom's best friend and near-brother.
    • At the end of the episode, Janeway heads off to debrief Kes on everything she learned about the Krennim. In the "Year from Hell" arc, when the Krennim did show up, they completely ignored "Before and After" and acted as though they never heard of the Krennim, nor that they had a warning that there would be a "Year from Hell".
    • Less than a year after it takes place, Kes ascends to a higher plane of existence and uses her near-godlike telekinetic powers to throw Voyager ten thousand light years closer to home as a sort of "thank you" for all of their years of friendship. This happened before "Year In Hell" and directly because Kes chose to leave the ship. Without that act, Voyager probably should not have reached Krennim space in Kes's lifetime. There was an an attempt to explain this in a Myriad Universes novel called "Places of Exile", where Voyager is damaged and lands on an alien planet to recoup during the events of "Scorpion", and they try to justify the 10,000 light-year leap by having the crew steal a Borg transwarp coil and jump away before Species 8472 destroys Borg space.
  • Scorpion (Season 3, Episode 26), a.k.a. The One Where Starfleet JAG Corps Is Apparently Completely Okay with Protagonists Committing Treason.
    • By allying herself with the Borg, Janeway commits at least three crimes that should have gotten her incarcerated in Voyager's brig for the rest of the trip, and sentenced to life in prisonnote  once they got back to Earth. Providing tactical and material support to the Borg by itself constitutes aiding the enemy (or full-on treason if we take what Jack and the other Augments were nearly charged with in DS9: "Statistical Probabilities" as an In-Universe legal precedent). On top of that, she's in direct violation of standing, lawful orders given by a superior officer (Admiral Nechayev in Star Trek: The Next Generation: "Descent"), which require her to damage the Borg at all opportunities. And because the entire raison d'etre of the Borg is and always has been to assimilate or destroy every thinking creature in the galaxy, Janeway is also an accessory to genocide against the Undine and any and all other neutral powers that the Borg were able to assimilate because she assisted them.

      And let's not forget that she committed these crimes after a single encounter with a single individual Undine (who was probably lashing out in fear, having been left behind on a derelict Borg cube) and used the word of an untrained psychic to extrapolate the possible intent of an entire species. Hardly conclusive evidence, wouldn't you say? The correct solution is to either attempt peaceful contact with the Undine and help them out, or just stay well clear of the whole damn mess. Helping the Borg shouldn't have even been on the table, and Chakotay should have relieved her of command right then and there for entertaining the possibility. Voyager's crew are in turn accessories to all of the above for helping her. If ever there was evidence of Protagonist-Centered Morality in Trek, there it is.
    • It could be argued that Janeway legitimately believed Species 8472 was a far bigger threat to the galaxy than the Borg...except she later agrees to give them the technical details of the nanoprobe weapon — the only known weapon to which 8472 is vulnerable. BOTH species have shown nothing but hostile intent toward the Federation, so she has the bizarre distinction of having given aid to both sides of a war in which each belligerent is also in a de facto state of war with the Federation.
    • Making this more stupid, Star Trek Online revealed that 8472 has become a major threat to everyone in the Alpha Quadrant now that their hat is infiltrating governments and manipulating them. Helping them might very well have doomed the entire Federation and galaxy because 8472 could cripple any defensive measures while simultaneously using powerful tech to kill every living being.

    Season 4 
  • Random Thoughts (Season 4, Episode 10).
    • The basic premise of the episode is that while visiting a planet, B'elanna has a mildly violent thought, which causes a chain reaction that incites one of the natives to commit a violent crime. As punishment for this crime, B'elanna is sentenced to have the violent thought removed from her head. How is this helping anyone? It's not going to prevent her from having more violent thoughts, the interrogation and procedure itself is probably creating more violent thoughts as it occurs, and it definitely doesn't help the victims. The best thing to do would be to simply banish the crew from the surface, which isn't a huge problem because they're leaving the system forever anyway. And given that such "random thoughts" do such serious damage, it's amazing that the inhabitants haven't implemented some kind of blockade, screening, or warning system for passers by who might accidentally run afoul of this.
    • The whole situation could have been avoided if the aliens had, y'know, actually bothered to tell the Voyager crew about this before they were on the planet. Pretty simple bit of conversation, really: "Hey Captain, since we're telepaths and all, we're trying to keep out violent thoughts; could you avoid having any while you're down here?" "Yeah, sure, that's some pretty handy information, good thing you told us." *to comm* "Hey B'Elanna, you might want to stay on the ship for this one."
    • What's even more ridiculous is that a race of warp-capable telepaths have apparently so little mental discipline that B'Elanna's bad thoughts constitute an overwhelming urge to act out said thought. And this is from people who actively visit a black market just to experience violent thoughts. Honestly, it's a wonder this species didn't completely annihilate themselves when they made first contact.
  • Hunters (Season 4, Episode 15). B'Elanna and Chakotay are both devastated by the news of the Maquis being exterminated. Chakotay laments about having to inform the other Maquis onboard. But does anyone inform Janeway that a forth of her crew is about to need some serious moral assistance soon? Not onscreen. Do we even see Janeway giving Chakotay—her best friend—any sympathy about his dead comrades? No. Instead, we see him comforting her about her botched love life! The fact that Chakotay himself seems more interested in Janeway being available than his dead friends is also a wallbanger.
  • Prey (Season 4, Episode 16): Dying to protect 8472 would have been dumb enough, but Janeway wanted the crew to die for that species when they knew that 8472 was going to die no matter what they did. That's a Senseless Sacrifice. Up until then, Seven had tried to destroy Voyager many times. Janeway always forgave her. On this occasion, Janeway tried to destroy the ship, Seven saved the ship, and Janeway never forgave her.
  • Vis A Vis (Season 4, Episode 20). One of those episodes where the reset button wasn't hit, yet the crew wasn't any better off for it. When the episode ends, the crew knows how to use Coaxial Warp technology, which means that they don't have to travel through normal space to warp, and can travel further faster. Unlike other examples where the crew got a new source of propulsion, no specific reason is given why they can't just use coaxial warp in the next episode. Yet in the next episode, they forget all about it.
  • The Omega Directive (Season 4, Episode 21):
    • As a means of explanation: Voyager detects a particle of energy that holds both the promise of virtually limitless power, and incredible destruction - the particle can power an entire warp capable civilization when synthesized correctly. If used incorrectly, the particle can destroy subspace for light-years, thus making warp travel impossible and destroying space faring civilizations. Because of this, all Starfleet personnel are authorized to do anything to destroy Omega, and the entire Federation Charter, including the Prime Directive, is superseded by this. Voyager detects a store of Omega large enough to destroy 1/8th of the galaxy. Janeway then goes on a mission to destroy this store of Omega. However, there are several problems with this.
    • The lack of communication with the aliens. Seven spends a few minutes asking one they patched up some technical questions, but other than that nobody tries to talk with the aliens, reason with them, or anything, which is saying something given how Janeway often tries to talk to aliens even when they're killing and mentally/physically assaulting her crew. Janeway just beams in, takes the molecules, tries to destroy them, and says nothing to the aliens about why she's doing it. It never occurs to her to tell the aliens exactly what it is they're dealing with, or that the aliens may just voluntarily give it up if they know just how bad what they have is. It never occurs to her that this civilization may just recreate the experiment after she's left, given they already did it once, and that talking to the aliens may get her more information on this than simply destroying the existing stores. She never stops to think of the possibility that if they do manage to recreate it, she's now made an enemy of a species with a power source greater than anything in the Federation, one which they will now be quite unwilling to share. And if they botch a second experiment, she won't find out about it until a few months down the line when she wakes up one day to find that Voyager's warp engines suddenly don't work, and they're too far away to do anything about it.
    • Nobody thinks that it might be a blessing in disguise that they can suddenly throw out the entire Federation charter that has been hampering them all journey. With this new interpretation of the Omega Directive, Voyager can ally with anyone, use any tech, make any trade, so long as it can be construed as preventing the creation of, or destroying, Omega. Indeed, it's not even that much of a stretch: this civilization has declared their intent to create Omega, it's very possible that other civilizations could be going down the same path. Suddenly, there's a real need for Voyager to get back home, and/or get resources from anywhere to stop this. Yet the next episode, the Reset Button has been pushed once again, despite this being one time where it would actually be more beneficial to Voyager not to push it.
  • Hope and Fear (Season 4, Episode 26). At the beginning of the episode, Janeway and Seven are engaged in some kind of phaser frisbee match. After Janeway soundly beats Seven, the latter complains that with her superior abilities, she should never have lost, and that Janeway was making impossible shots. When Janeway explains how she used physics, sound and indirect visual cues to determine the location of the frisbee when she could not see it, Seven dismisses it out of hand. It is completely implausible to her to use any of her senses other than sight to determine where her target is. Even with sight, it never occurs to her that there might be indirect visual cues to tell her where the object is even if she cannot see it herself. And you thought Khan getting schooled by forgetting that space was 3 dimensional was bad.

    Season 5 
  • Once Upon a Time (Season 5, Episode 5):
    • Flotter is a character from a holodeck game. Neelix wants to give Naomi a Flotter doll. Harry programs the replicator by memory, because he played the game 10 years ago. The computer should already know what Flotter looks like.
    • The holodeck as common tech should be only about twelve years old right then. In the first two seasons of TNG, every time we saw a character go into it, they said things like "Wow, I've never seen anything like this before!" At the end of this episode, Janeway says that she too had played the Flotter holoprogram, and it is clear that she means in her childhood. She has been in the fleet long enough to work her way up to captain, and does not look young. At best, her remembering a holodeck program from her childhood makes about as much sense as saying "Remember when you sent that Tweet after Bucky Dent hit his home run off of Mike Torres in the 1978 playoff game, and I texted you that we should celebrate by buying new leisure suits from eBay?"
  • Timeless (Season 5, Episode 6). The Quantum Slipstream Drive. In a very similar way to the Warp 10 engine, once the Voyager crew hit a minor obstacle they rip it out and forget about it. It was established that it takes approximately 15 seconds for the phase variance to show itself and it was also established that a simple calculation in-putted into the computer will safely collapse the vortex. Voyager travelled 10,000 light years in its failed jump, or in other words, 10 years closer to home. Even with the conceit that the materials had a limited shelf life, there is no reason given why they can't try it again. The obvious answer of using the Drive for 10 seconds a time and getting home in a day is completely missed, as is modifying the Delta Flyer to send a message back to Earth given how we have already proven it can transverse the Slipstream completely without incident. If this seems like Fanwank to anyone, remember that back in Hope and Fear we have already seen that Voyager can navigate a Quantum Slipstream for limited periods of time without any negative effects whatsoever, and that one wasn't even designed to be compatible with a Federation Starship.
  • Nothing Human (Season 5, Episode 8). Strap yourselves in - this is going to be a long one.
    • The Cardassian here is clearly meant to represent Nazi doctors. Slight problem: the results of hideous Nazi experiments regarding decompression were vital in the early stages of space programs. Similarly unpleasant experiments revealed a great deal of information about hypothermia. None of this data was simply discarded. One would imagine a show about spaceships would try to remember something like that. More notably, a real-life example was Unit 731, a department of the Japanese research and development military branch that also did terrible things. They weren't prosecuted by the US in exchange for copies of the info they learned, both medical advances and weapon related. Around 450 thousand people were killed by them.
    • The Doctor saves B'Elanna's life with the help of a hologram modeled after an infamous Cardassian doctor. The Doctor later decides to delete this hologram, a hologram that appeared just as sentient as the Doctor himself! The Doctor also deletes all the data that saved B'Elanna's life in the first place, condemning to death anyone else who gets into that situation.
    • It was far stupider for B'Elanna to refuse the treatment because of its source. The doctor did the right thing by ignoring her wishes. But there was no reason to delete the medical information that could be used to save more lives. Sure, the way the information was gotten was terrible, but throwing it away isn't going to help the Bajorans who died.
    • This isn't the real Crell Mosset — it's a hologram of him. Though he has some of the sideways beliefs of the original Crell Mosset, he is not Crell Mosset any more than the Doctor — that is, Voyager's official EMH — is Lewis Zimmerman. Crell Mosset's hologram doesn't even have the memories of the atrocities the real Mosset committed; and the ill-gotten data was well-dispersed, as it was already in Voyager's database. Even stranger, Mosset's information should already be in the ship's computer, so the Doctor should already be fully aware of the data and wouldn't need to make a hologram of Mosset in the first place. The real ethical question at hand was whether to delete Mosset's program after fixing B'Elanna; but the episode treats that as an easy decision and fixing B'Elanna as the difficult one.
    • The worst part is — the holo-consultant points out all of this! He himself tells the Doctor that he's not Mosset, and is just a representation of him! Hell, the only way it could have been worse is if the hologram pulled a Tuvix and desperately pleaded for his life. Then again, that didn't even work for Tuvix, and the remaining crew liked Tuvix better than the crew members he briefly replaced. Even worse, there was nothing stopping the crew from changing Mosset's appearance to something different if they were so bothered about him.
    • Also, they managed to invert Take a Third Option by taking the worst of both choices - use the data that B'Elanna was morally opposed to, and then delete it so that it can't help anyone else who has different moral standards!
    • How about the disturbing implication from all this, that their computers can create a fully sapient individual with his own personality quirks and desires (Crell wishes to write a paper on the whole parasite matter with the Doctor for example) which can then be immediately deleted permanently with a single verbal command. Even computers today usually have an "are you sure?" before you erase a file for good.
  • Course Oblivion (Season 5, Episode 18):
    • The "living deuterium goop" that the crew encountered in the fourth-season episode "Demon" somehow replicates a fully-functional, warp-capable, EMH-equipped, fifteen-deck, 700,000-ton anti-matter powered starship. And no, they didn't build it, the goop somehow formed itself into a working starship.
    • The replicants themselves. The first two replicants copied didn't know what they were at first, but the Harry Kim replicant caught on. After the entire crew is replicated, they clearly realize what they are since they don't seem pissed Voyager is abandoning them. Then, against all logic, this crew of replicants, including the original Kim replicant, forget they're replicants. Furthermore, it was a point that the original replicants could only breathe the totally inhospitable vapor that passed for atmosphere on their planet, yet these replicants go around breathing human air like it's nothing. Then they go back to breathing an approximation of the death air with no transition.
    • The Shoot the Shaggy Dog nature of the episode. The replicants somehow built a spiffy new warp drive that killed all of them due to radiation harmful to their kind, ended up flying back to find Voyager, and died before they could make it. It amounts to a footnote in Janeway's logs.
  • The Disease (Season 5, Episode 19): The episode reveals that you need medical clearance to sleep with an alien. In itself, it would make a lot of sense ... but this is One Shot Revisionism. In no other episode does anyone get in trouble with Starfleet solely for sleeping around with aliens. Harry gets everyone on his case about it. He's the only person in the history of Star Trek to be berated by his crew for sleeping with a pretty alien girl. To make things even worse, in Next Generation's "Dauphin", when Wesley caught the eye of the alien girl who would unite her people, Picard told him that, ordinarily, a ship's captain has no business getting involved in the romantic affairs of his crew (even if aliens are involved). The only reason he was getting involved in Wesley's case was because the girl in question had an overprotective and dangerous bodyguard, making Picard concerned about Wesley's safety as well as a possible diplomatic incident. The Voyager crew have no such excuse.
  • Equinox, Part 1 (Season 5, Episode 26): Janeway tries to get Captain Ransom to abandon the USS Equinox, long before it was established that he was evil, by citing a regulation that states that in a combat situation involving two or more captains of equal rank, command of the fleet falls to the ship with tactical superiority.
    • First off, let's discuss this rule. The obvious spirit of this rule is that, in a battle situation, it stops an ego contest between two captains and establishes a clear chain of command. For example, in Star Trek: First Contact, Picard is able to take command of the entire fleet battling the Borg because the admiral he's disobeying is now dead, and the Enterprise-E is without question their biggest stick. Janeway is using the letter of the law in what is only barely a combat situation (the aliens are a threat to the crews, not the ships per se), and she's using the opportunity to make sure Ransom will be incapable of ever reassuming command by removing the ship he's commanding. It also shows quite a bit about what sort of woman she is that she almost immediately looked for a way to be able to give orders to someone of completely equal rank.
    • Now let's discuss the reaction. Ransom naturally doesn't take this lying down — he's heading home and Janeway's an obstacle — but even if we take away the fact that he's evil, would any captain, Janeway included, behave any differently? Imagine if she pulled this on Captain Kirk of the original Enterprise. Same situation, Voyager has priority. Could you imagine how many levels of fuck off Kirk would employ if Janeway told him to just happily abandon his pride and joy on the basis of some questionable regulation drawn up thousands of light years away? Even better, imagine for a moment that it was a Galaxy-class, Nebula-class, or other top-of-the-line ship that had stumbled across Janeway. Do you suppose for even a nanosecond that she would be willing to let that captain scrap Voyager for parts and accept a non-command position after everything she had been through keeping her ship and crew intact on their way through the Delta Quadrant? Of course not.
    • Unrelated to that issue, but Ransom was dragged in by the Caretaker same as Voyager, and yet, departing from the exact same point, managed to fly off on a tangent that allowed them a completely different adventure. He even admits not knowing the Kazon, when the Array was technically in Kazon space.

    Season 6 
  • Equinox, Part 2 (Season 6, Episode 1):
    • Janeway's interrogation of the Equinox crewman was nothing short of attempted murder. Seriously, watch that scene. There's absolutely no ambiguity. She was fully prepared to allow an alien to kill a defenseless man in her custody. That man would have died if not for Chakotay's intervention.
    • What really makes this suck is that Ransom is essentially Janeway, sans the plot coupons she's been receiving the entire series up until then. Janeway is pissed off at Ransom for doing what he did, but seriously, the only difference between them is that Janeway has been the recipient of numerous pushes of the Reset Button when faced with an alien species she's pissed off, a food crisis, a fuel shortage, etc. She single-handedly owned the Borg, back when they were kind of threatening. None of this is plausible, and by rights Janeway should have met her match back in Kazon territory. It's kind of hard to sympathize with Janeway about doing the right thing, when a lot of the times she's gotten the good end of the stick on something, it's despite not doing the right thing.
    • At the end of the first part, Captain Ransom said that they'd need 63 more life forms to get home. In this part, he describes the power they got from one alien — it allows the Equinox crew to travel 10,000 light years in two weeks. Assuming that Ransom was originally stranded in the same place as Janeway, it would take 7 life forms and 14 weeks for them to get home. How did they work out 63?
  • The Voyager Conspiracy (Season 6, Episode 9):
    • All of the mutinous accusations against Janeway and Chakotay are eventually revealed to be figments of Seven's imagination. However, Neelix's sensor data is completely forgotten. Problems:
    1. Not a single Maquis gives even one throwaway line of concern over a fully armed Cardassian warship in the Delta Quadrant. This is one time the Maquis Aborted Arc would've been useful. It could have made it all the way to Borg Space before encountering a significant challenge.
    2. No explanation is given for the tractor beam focused on the reactor room of the Caretaker's array.
    3. Seven directly asks Tuvok, but there is no explanation for Voyager needing a Starfleet WMD for the Maquis ship that was no bigger than a runabout and too fragile to survive the trip to the Delta Quadrant. Nor does he explain why he set the torpedoes twice as strong as necessary. Even worse when Star Trek: Insurrection reveals that subspace weapons are illegal. Tuvok's sole answer is an aside glance, presumably so Seven doesn't accidentally get him into a war crimes tribunal.
    • Also, Photonic Fleas? Seriously? The definition of "photonic" is the technical application of the science of light. The definition of "flea" is a tiny, wingless blood-sucking insect. These Photonic Fleas have wings, are made of light, and show no inclination to try sucking Seven or Janeway's blood because, according to Seven, they consume plasma particles - which should mean they eat nothing but superheated gas. The name is misleading.
    • The real problem is that the suggested conspiracies are too far fetched to be believed for even a second. The whole episode is basically "Voodoo Shark: The Episode". Fact is, at that point, Voyager was where they were through pure dumb luck, and everyone on the ship knew it. Any organization that would be clever and resourceful enough to purposefully manufacture all the Deus Ex Machinas, Hail Mary's, and contrived coincidences that got them to that point would be clever enough to just avoid all that hassle, and have gotten the catapult that was allegedly the motive behind the conspiracy from the start. The closing lines of the show pretty much sum up the entire episode, when Janeway states that Seven was malfunctioning, but Janeway herself and Chakotay had no excuse for their stupidity.
  • Memorial (Season 6, Episode 14):
    • The very concept of a mass-genocide memorial, which mind rapes anyone who encounters it. Remembering a genocide is all well and good but that does not in any way, shape, or form justify the mind-rape of innocent people. Those people could have just set up a plaque as a memorial but they deliberately went with the mind-rape machine, losing any sympathy they could have gained. What's worse is that no one even knows if it's an accurate portrayal of historical events. And in case you are unaware, according to official figures PTSD causes an average of 22 veterans in the United States to commit suicide a day, which potentially makes this memorial a hundred times more deadly than the massacre it was built to remember.
    • Not only did Janeway not destroy the grossly unethical memorial that traumatized countless millions destroyed (or at the very least, shut it off), but she also ordered that memorial repaired. At least she put up a warning beacon.
    • Speaking of which, the warning beacon faces the same problem the memorial itself faced before, and probably will again. Like the memorial, eventually it degrade and fail. Either the beacon will malfunction, which most Federation technology does if you so much as sneeze on it, or its orbit will decay. And then the memorial itself will probably crap out again in a few centuries, if not sooner because all they did was patch the thing, and some other unlucky crew will have to deal with that crap.
  • Good Shepherd ('Season 6, Episode 20), an analogue to TNG's "Lower Decks":
    • Three minor crew members are taken by Janeway on a mission in order to become more productive members of Voyager. The first is Mortimer Harren, who has five degrees in theoretical cosmology but slacks off at a sensor station at the bottom of the ship. The second is Tal Celes, a sensor analyst who can't do 24th century math to save her life. The third William Telfer, a hypochondriac who avoids every away mission by complaining to the doctor. Instead of simply switching the first two crew members around (even with the excuse that Harron is lazy and won't work), and after blatantly ignoring the advice given to her by Seven, she elects to take all three people (who have never been on an away mission before) to investigate an anomaly - pretty much the only consistent source of danger in the show. Really, Janeway?
    • The episode portrays Mortimer Harron (the man with the cosmology degrees) as the villain of the episode. That's right, a character who calmly explains to Janeway and his fellow crewmembers that his life was destroyed because of the main cast, is stuck in a position that he has no love for whatsoever, and happens to be the only character in the episode who acts in a sensible manner (he fixes the engines, gives logical theories and almost sacrifices his life to save everyone else) is shunned by a paranoid hypochondriac and a woman who can't even do her job properly. What.
    • At one point, an unknown lifeform beams aboard the Delta Flyer and begins interfacing with the ship's systems, which causes massive power fluctuations. Janeway attempts to reason with it (which doesn't have any effect), before Harron pulls out a phaser, killing it and stopping the drain on the ship's systems. Janeway then proceeds to severely admonish him, saying that the creature could have been friendly. At no time does she bother to take into account that the creature couldn't understand her and was actively threatening their lives. At best, the creature would have sapped all the power out of the Flyer (which would have killed everyone onboard due to a lack of life support), and at worst, it would have destroyed the ship, or at the very least made the atmosphere unbreathable. Yet, the audience is supposed to be on Janeway's side as she chews out an ensign who just saved the ship from certain destruction because she's playing fast and loose with the Prime Directive... why?
    • Janeway's rationale in this whole thing is that it will help them become more productive, but this flat out will not work as she planned it. Mortimer Harron was never motivated to change to a more productive job. This isn't going to change his mind. Tal's problem wasn't motivation but skill — she simply did not have the proper knowledge to do her job, and this would not teach her. Finally, William's problem is psychological, and the only reason he's "cured" is because he's attacked by one of the aliens. In other words, in order for Janeway's plan to work, she had to risk their lives. Scaring someone straight is one thing, but damn Janeway, that's harsh.
    • William being cured is a wallbanger in itself - hypochondria does not work that way.
  • Fury (Season 6, Episode 23):
    • Despite being friends for the past thirty years, Janeway forgets when Tuvok was born, and sloppily tries to discover what his birthdate is so she can bake him a cake.
    • Why did Kes attack Voyager and kill Torres before jumping back in time? She has no reason to think that the crew had a grudge against her. Besides, the last time she was seen, she was being helped by Janeway, Tuvok and the bridge crew, and seemed at peace with herself.
    • The episode reveals that Ensign Wildman and the Doctor created anti-Vidiian laughing gas to use as a countermeasure. Why, then, was this technology never used or deployed against the Vidiians at any point during the first two seasons? It would have been very helpful during several encounters with them.
  • Unimatrix Zero, Part 1 (Season 6, Episode 26): The Borg Queen has confronted Janeway, and wants her to reveal the secret frequency that Unimatrix Zero is operating on. Janeway refuses, causing the Borg Queen to demonstrate how ruthless she is ... by destroying all of her ships where she cannot hear one or more of her drones. Apparently the Borg Queen went to the same computer education course that LaForge went to in TNG's "Contagion" - you know, the one that didn't teach him how to do a basic system restore. 1) Why should Janeway care if the Borg Queen is destroying 99% of her troops to get to the traitorous 1%? These people are POW's at best - Janeway has no reason to believe that these Fifth Columnists will be anything other than executed once she reveals where they are. Given that these drones are going to be executed anyway, the choice becomes one between a) all the good guys are executed, or b) all the good guys are executed, but so are 98% of the bad guys. 2) Has the Borg Queen ever heard of a binary search algorithm? This shouldn't take more than a few days at worst, if that. It can't be worse than throwing out 99% of the collective just to get at the 1%. If we have a bad network connection on the Internet now, we don't just throw out the entire network because one connection is bad, nor does it take us an inordinate amount of time to find said connection either. Then too, this is the Borg, and after TNG, it isn't like they were known for their common sense...

    Season 7 
  • Unimatrix Zero, Part 2 (Season 7, Episode 1):
    • The convenience of Janeway, Tuvok and Torres's assimilation. When Picard was freed from the Borg, he still had enough technology in his brain to tap into the Collective when in proximity to a Cube (First Contact). When Seven of Nine was freed from the Borg, she needed a false eye, had a bunch of implants both insidde and out, and had enough nanomachines in her blood to do whatever the plot required. The Borg from "Unity" and the Borg children the Voyager crew later came across were still covered head to toe in various small pieces of tech that they couldn't remove. These three? Completely recovered. Not a trace of Borg tech or a single nano to be found. Amazingly enough, the scriptwriters manage to supersede even this piece of nonsense by revealing the fact that now a simple injection is enough to completely shield you from the Borg Hive Mind for twelve hours... given how badly that destroys the entire premise of the Borg it's no wonder they were killed off during Endgame.
    • Speaking of destroying the whole premise of the Borg how about Voyager's revelation that the Borg have absolutely no creative thinking and can only gain knowledge through assimilation? They were shown to be absolutely helpless against Species 8472 until Voyager helped them. The Borg have shown the ability to scan and work things out for themselves numerous times. It's where their ability to adapt to new weapons comes from and they have been shown to hack into enemy computers (Q Who and First Contact respectively.) The Borg must have started out as a normal species once upon a time, right? They had scientists who developed their first interstellar ships and weapons powerful enough to actually start attacking other civilizations? It's a pretty ridiculous concept that a species whose ultimate goal is perfection would have eliminated the ability to actually improve their own technology in order to attack and defend against new enemies.
    • There's a firefight between Voyager and a Borg Tactical Cube — a more lethal version of the type of ship that has twice effortlessly curb stomped the best that Starfleet could throw at it — and it's the cube that ends up having to limp away to lick its wounds?!
  • Repression (Season 7, Episode 4):
    • It is implied that cinemas no longer exist ... what?? The Holodeck probably would have killed a lot of business, but 1) Holodecks were stated to be brand new technology during TNG and as such, not everyone should have regular and reliable access to one a mere decade later. 2) Sometimes you won't want to exert yourself playing through a story and may just want to kick back and watch a story unfold — pretty difficult to be lazy in a fully interactive 3D recreation of D-Day for example. Laughably, an earlier episode implies televisions no longer exist; as if everyone has enough room in their house for a fully working holodeck or something. Even with the fanwank that cinemas or televisions can be created in the holodeck for just a purpose, a later episode laughs at this suggestion by having B'Elanna chew out Tom for programming a cinema on the holodeck, calling it "a 3D projection of a projector to create a 2D image".
    • There's even an instance where Harry questions why anyone would read a book. Captain Picard may be willing to do everything he can to avoid genociding the Borg, or killing crystalline entities that eat planets, but he'd probably eject Harry out the airlock without a second thought for that comment. Although he'd probably be willing to do that simply because he might know that killing Harry is only a minor inconvenience for him.
  • Human Error (Season 7, Episode 18):
    • Seven, in one episode, changes from her normal love-is-irrelevant self to being in love with Chakotay. This was never reset. They never appeared to even like each other as friends before then. You could count on the fingers of one hand how many times they spoke outside of a professional setting. He didn't approve of Janeway's decision to sever her from the collective, and there was nothing to suggest that he ever changed his mind about that until "Endgame." They also had zero chemistry in "Natural Law". It's one of the most blatant examples of Strangled by the Red String in TV history. Yes, Chakotay's actor would've left if he didn't get more storylines, but it didn't need to be Shipping! Killing Chakotay off would have been preferable, since he was Out of Focus anyway.
    • Know who else the Chakotay/Seven romance frustrates? Chakotay/Seven shippers. Seven and Chakotay had potential to be a very interesting couple, for many reasons. Their backgrounds are polar opposites. They're both collected and monotone on the outside, but emotional volcanoes on the inside. Chakotay's the least-Borg person on Voyager, so it makes sense for Seven to desire him when she's starting to desire her own humanity in Season 7. Their interactions, platonic or romantic, could have been great. Yet instead, they barely spoke for most of the series, and what we saw of their romance was limited to cliched dates and kissing scenes. It's no wonder the vast majority of C/7 fan fiction is dedicated to giving their relationship a back-story.
  • Author, Author (Season 7, Episode 20):
    • The TNG episode "The Measure of a Man" had Data as the focus of a legal dispute — his status as a sentient being is the crux of the episode, and if he loses, he'll be disassembled and studied by the mandatory Jerk Ass scientist who sees him as a an object, not a person. (Not that Dr. Pulaski ever got slapped for that kind of behaviour — onscreen...). The episode ends with what should be a precedent of recognising Data as a person. Given that Data and The Doctor are both artificial beings who are demonstrably intelligent and sentient, it seems logical that an enlightened, forward thinking society like the Federation would thus give The Doctor a free pass ... logic doesn't enter into it, though. The Doctor's case is settled on other grounds, leaving his personhood undecided. Later, a whole group of EMH Mark Is are shown working in a mine, all of whom could potentially gain the level of awareness that The Doctor has — so it looks like EMHs are de facto non-persons. We aren't supposed to be happy about that, mind you — but how did things get so dark in the Federation in less than 14 years?!
    • It gets stranger. The EMH got into this because he had written a holonovel and wanted to take it back for revision, and his publisher was refusing because he wasn't a person. (The publisher would've deserved the libel suit it would've eventually gotten if it had won.) The Federation did not declare the EMH a person, but they did say that he is legally an artist and thus has copyright control over his work. And you thought applying the Fourteenth Amendment to corporations was bad.
    • The existence of copyright at all. Economics in the Trek universe works on post-scarcity production, meaning that there is no private ownership. So why does copyright still exist if information is one of the post-scarcity resources we have right now? If anything, a society that prides itself on freedom and the free exchange of information like the Federation should have laws against trying to restrict the copying of data! However, even in post-scarcity, people may still want creators and inventors given proper credit and recognition, though the Doctor was technically being credited for his work, just not in a way he approved of.
    • The saddest part is, Picard's biggest argument back when he was defending Data was that declaring Data non-sentient would set a bad precedent!
  • Endgame (Season 7, Episode 25 & 26):
    • A future version of Janeway travels back in time to get Voyager home earlier. (It seems that the death of Seven of Nine in transit is, in hindsight, completely unacceptable to her, far more so than the deaths of everyone else who has died throughout the series!) It's been established in prior episodes that the future Federation is constantly monitoring time for this kind of thing (the Temporal Prime Directive), yet when Janeway beams herself back in time and affects the lives of trillions of beings at the least by proxy and her entire crew on purpose, we don't get so much as a peep. Mind you, this is after Janeway's temporal antics had driven one captain crazy and even his first officer thought their temporal meddling was rather annoying.
    • There is an earlier (by definition) episode in which a future Tom Paris and Harry Kim go back in time to save those left behind. They get berated for it by Janeway. But at the end of season 7 and the series, with no natural end in sight, a time travelling Janeway comes back, destroys a critical portion of the Borg Collective, and sacrifices her life to provide a shortcut home. Under the circumstances, this must be a Deus ex Machina; a natural ending for season 7 would've been No Ending, or else something like TNG's "All Good Things".
    • Future Janeway also ignored how it would affect people born to crewmembers after the time she jumped in. These people may never exist or may have wildly different lives if they do, but that doesn't seem to matter to her, and what we see of these people (Miral Paris, Harry Kim) indicates that they're perfectly fine with having their lives and memories erased by Janeway.
    • At the end of the episode, Voyager (and the Borg sphere chasing it) flies out of a heretofore-unmentioned Borg transit wormhole - which exits directly in front of Earth. Not only is this patently absurd given the events of Star Trek: First Contact (in which a single Borg cube destroys part of the Federation fleet before being taken down), but it retroactively makes episodes like TNG's "Best of Both Worlds" pointless - if you've got a direct wormhole to Earth, why waste time travelling through the galaxy when you could jump directly to the source in minutes?
    • Star Trek has never been internally consistent with its rules on time travel, but rarely does it derail the entire plot of an episode. Future Janeway is able to go back in time, change her entire history is every conceivable way and still be perfectly fine by the end of it. The Borg Queen on the other hand is adamant that if she kills past Janeway, future Janeway cannot come back in time to kill her... even though past Janeway is not technically the past Janeway of future Janeway, because future Janeway has already metaphorically killed off her actual past self by changing history. And it shouldn't matter anyway, because future Janeway has already proven that changes to this particular timeline do not affect her. Its a logical conundrum that hurts the soul to try working out how both of these things could possibly be true. To put it another way, this is like saying that murdering Chris Pine's Kirk would delete William Shatner's Kirk.
