* ... Sometimes, it's amazing that this series even had a ''chance'' to be as [[GrowingTheBeard good as it was in season six]] with all the rampant Wall Bangers flying around in season one.
** "[[Recap/StarTrekTheNextGenerationS1E2TheNakedNow The Naked Now]]" is the supreme Wall Banger episode in the hit-and-miss first season. The inhibition-destroying disease from the [[Series/StarTrekTheOriginalSeries original series]] episode "[[Recap/StarTrekS1E4TheNakedTime The Naked Time]]" hits the ''Enterprise-D''. During the story, Dr. Crusher is somehow unable to recognize a ''dangerous disease'' with a ''known history'', nor does she find it in her medical database; but Commander Riker finds it in Kirk's archived [[CaptainsLog Captain's Logs]], which are more than 70 years old. This implies that Dr. [=McCoy=] or Starfleet Medical kept ''terrible'' records. And ''that'' is nothing when you consider that ''Data gets drunk off of the molecule!'' A sentient ''machine'', made (mostly) of metal and plastic with a positronic brain categorically different from our own, gets drunk off of a molecule that ''itself'' only causes drunkeness because of its similarity to the alcohol molecule. The whole "Riker found what Doctor Crusher didn't" is nothing compared to that.
*** [[LampshadeHanging Pointed out]] by the Captain and [[HandWave handwaved]] by Data.
--->'''Data''': I have pores. Humans have pores. I have fingerprints. Humans have fingerprints. My chemical nutrients are like your blood. If you prick me, do I not... leak?
**** By the way, Data ''doesn't'' leak: if you chop off his arm he has a snarl of wiring and metal "bones" — with empty gaps of air in between. And if you rip off or cut his skin, it just flaps there like wrapping paper, revealing the circuitry underneath. So the Trek writers accomplished the impressive feat of making even a handwave that didn't make sense actually contradict canon.
**** The original idea for Data was that he would have organic components inside, leading to comments like that and another where he mentions that he imbibes a form of lubricant/nutrient to keep those parts functional.
*** Not to mention the mutation that caused the disease to [[HotterAndSexier increase the libido of the crewmembers, or something]]. In "The Naked Time" it lowered inhibitions -- Riley, proud of his Irish ancestry, imagines himself as an old High King singing love songs; Sulu, who fancies himself a fencer, becomes one of Literature/TheThreeMusketeers; Spock, forever forced to bury his emotional side has it come to the surface leading to him losing control and ''weeping''; Nurse Chapel admits her love to a man who can never return it; finally, Kirk, burdened by his position of Captain, breaks down and admits the enormous pressures he's under and how being around [[LoveInterest Yeoman Rand]] is painful. What happens in "The Naked Now"? "You're kinda hot, let's have sex!"
*** However, there is a potential justification for this: The virus MUTATED. As it did, its effect must logically be altered somehow, causing a slightly different effect in most of its victims. Still doesn't excuse most of the stupidity, but at least makes this part potentially less stupid. Of course, this merely shifts the blame to the writers, who choose "Drunk people are funny" over "Let's explore the characters in depth, it'll be a good plot device to familiarize the viewers with these new characters."
*** And "The Naked Time" airing as the sixth episode of ''TOS'' was already pushing things, and using this one as just the ''second'' episode is even worse. Both the audience and the actors have barely gotten to know these characters, so how is seeing them act out of character supposed to be any fun for anyone? In particular there's Riker noting that Geordi is acting strange, making you wonder how he could know when they just joined the ship last week.
** In "Datalore", it's understandable for Lore to be dismissive of [[CreatorsPet Wesley]] to slip up his disguise. But the crew is dismissive as well, causing Wesley to basically shout it out to them! And even that fails. The crew's, and especially Picard's, disbelief is inexplicable, since all Lore would need to do to impersonate Data is incapacitate him and switch outfits... which is exactly what he had done, and what he would eventually do again.
*** It's even worse than that because Picard had sent Wesley specifically to check on Lore and Data and see if something was amiss. Why send someone to check if something is wrong if you're just going to dismiss them when they say they saw something wrong?!
*** Apparently Picard had no intentions of listening to anything Wesley had to say and the order just something he gave to keep Wesley occupied, given the degree he was dismissing Wesley. Which is certainly going to set you up with a headache as to why a starship captain who apparently had a record good enough to rate captaining the flagship for the Federation would give an order like that with no intentions of respecting what the person had to say.
** "Justice" makes a huge deal about how they can't just beam Wesley up and fly away because of the Prime Directive. Which rather begs the question of why openly visiting this pre-warp civilization in the first place was allowed.
* In "Loud as a Whisper," the great negotiator that the Enterprise is transporting is deaf and speaks through a telepathic chorus of aides. But, throughout the episode, people address him when he isn't looking by calling his name, and people speak directly to him with no-one else present, and he responds. That could have made sense if they meant mute - but they go to a lot of trouble to explain how he cannot process any sound.
* There is the honored JAG from ''The Drumhead'' who hauled Picard into a KangarooCourt for being a traitor and breaking the Prime Directive simply because he was objecting to her apparent desire to continue investigating his crew after the original problem was settled and an otherwise innocent crew member was accused of sabotage for being part-Romulan and not telling anyone. Thankfully, Picard wrecked her career by making a bold speech and tricking her into making a fool of herself in front of an Admiral. She didn't sound ''that'' much crazier then than she had all episode, though, and she had been considered honorable before, so it's a wonder it worked.
** Another Wall Banger here is that she had to turn into a GeneralRipper to make the episode work, and cement once and for all the fact that Star Trek legal procedures were copied wholesale from the '''Franchise/AceAttorney'' games.
** And let's not forget that partway through the trial the engineers (as in actual scientists) discovered that the explosion that kicked off the whole thing was caused by a defective seal. As in it was clearly an accident. Nobody was at fault. ''There was no crime.'' But the JAG officer is allowed to continue her crusade anyway and her assistants refuse to believe it was an accident, and purposely [[LyingToThePerp lied to their suspect about the cause of the explosion]] to try and get him to confess. Shouldn't they have been punished for trying to perjure the defendant?
** I don't believe that Tarses was a defendant at that point, he was only a suspect (though, to my eye, that's even a bit of a stretch, 'person of interest' is probably more accurate based on the evidence Satie had at the time). This means that she opened what was more-or-less an interrogation to spectators. Tarsis was suspected of treason, espionage, sabotage, and perjury[[note]]He lied in his application to Starfleet, meaning he falsified an affirmation[[/note]] AND SHE OPENED HIS INTERROGATION TO FRIKIN' SPECTATORS. There are so many ethical and procedural breaches here, that I wouldn't even know where to start listing them.
** Consider: the Federation flagship's warp drive is crippled. A Romulan plot is suspected. What is Starfleet's response? A starship delivers a bunch of officials, and then buggers off, leaving the still crippled Enterprise helpless and undefended should the Romulans show up.
* The episode "Contagion": the Enterprise contracts a computer virus from a ship, the Yamato, that had been infected with the virus after scanning an ancient planet for a legendary transportation technology. As a result, all of the ship's systems begin to malfunction, including turbolifts, life support, and replicators. It gets so bad that Commander Riker remarks that (paraphrase) doing ''anything'', no matter how seemingly harmless, could trigger the destruction of the ship or its crew. So they decide to go to the planet that the Yamato surveyed to see if they can understand the program that infected them better. They then ''transport'' an away team to the surface. Problem: all the computer-operated systems are failing. So, to get to the source of the problem, you use a device which relies on the computer disassembling, transmitting, and reassembling every subatomic particle of your body WITHOUT ERROR! * BANG*
** Speaking of that episode, check out Data's behavior; he ''throws Geordi from an electrified panel'' and gives a ''human'' reaction of embarrassed surprise and shock. He stupidly puts his hand through a ''rapidly-changing portal through space'' (good thing the "image" didn't change while his hand was in there). And look at his reaction to being reactivated after purging his systems of the Iconian program. This is supposed to be an ''emotionless'' android, correct? One ''incapable'' of mimicking or even ''understanding'' human behavior? Why is he acting like this?
** No one in the 24th Century seems to know how to ''do a system restore on a computer''. You forgot that there was a ''reason'' there's a protective archive in the computer core, Geordi?
** This episode was conceived and co-written by Beth Woods, a computer technician who worked and the Trek offices. The wall banger is not only suggesting that the chief engineer of the flagship doesn't know how to do Ms Woods' job, but that the tech-savvy audience wouldn't know either.
* "Time Squared" has a bad portrayal of both Captain Picard and Counselor Troi. Picard acts ''extremely'' emotional and forceful with everyone, including the future doppelganger of him who drives the episode. Supposedly, he's acting this way because it appears that the doppelganger abandoned the Enterprise to its doom, and the crew have no way of knowing what caused the ship to explode or why the doppelganger left until it happens. But Picard has been shown to take stuff like this more calmly in previous episodes. And even his stress can't explain why he ''nearly assaulted his doppelganger while he was recovering in sickbay in order to get answers'', even though Troi told him several times that the doppelganger couldn't answer. Nor does it explain his rejection of the notion that the doppelganger was him simply because he couldn't see himself performing the actions the doppelganger did - especially since earlier episodes have shown him to take stuff like this more calmly and open-mindedly... Troi flip-flops on whether she's sympathetic or appalled by Picard's attitude. She goes from near-accusatory admonishment of him for his aforementioned assault, to ''defending'' his assault and ''rejecting the concerns of the ship's doctor about Picard's state of mind as unnecessary''. So, she clearly saw how out of character Picard was and even told him off about it, but she sees no reason to be concerned about it? What kind of counselor is she? ([[InformedAbility Don't answer that last question...]])
* The Galaxy-class Starship is the pride of Starfleet, being its largest, most advanced, most powerful, and most capable capitol ship; and the ''USS Enterprise'' is the best of them. That's why I find it so annoying that the class in general, and the ''Enterprise'' in particular, have such a glass jaw. By my count, we have seen ''Enterprise'' destroyed no less than eleven times over eight years (''[[Recap/StarTrekTheNextGenerationS2E13TimeSquared Time Squared]]'', ''[[Recap/StarTrekTheNextGenerationS3E15YesterdaysEnterprise Yesterday's Enterprise]]'', four times in ''[[Recap/StarTrekTheNextGenerationS5E18CauseAndEffect Cause and Effect]]'' ''Time Scape'', ''[[Recap/StarTrekTheNextGenerationS7E10Parallels Parallels]]'', three times in ''[[Recap/StarTrekTheNextGenerationS7E24AllGoodThings All Good Things...]]'', and once-and-for-all in Film/StarTrekGenerations), only to be brought back by some combination of ResetButton and TimeyWimeyBall-with the obvious exception of ''Generations''. When she did finally fall, it was in a situation very similar to the one which killed her first Constitution-class predecessor. In fact, ''Enterprise D'' underperformed that ship by a laughable margin, considering Kirk's ''Enterprise'' was still heavily damaged from Film/StarTrekIITheWrathOfKhan, was operating under heavy automation with a crew of five, and didn't actually have the capacity to raise its shields at the time-and she ''still'' managed to give as good as she got from a Klingon Bird-of-Prey.
** This is a combination of InformedAbility, ForgotAboutHisPowers, IdiotBall, IdiotPlot, and several other [[ContrivedStupidityTropes induced stupidity]] tropes. On paper, the Galaxy Class was the most powerful ship ever built by Starfleet at the time. In practice, it was the WorfEffect embodied as a ship: whenever it was brought up that something was a match for/X times as powerful as a Galaxy Class, it was a way of setting up an unknown enemy as a credible threat. When it came down to actual fighting, the GC never did hold up very well on screen, generally firing one or two shots, and either winning or losing in those handful of shots. The only extended fight we see the Ent-D win in the series is in The Best of Both Worlds, and that is through sheer dumb luck. You could expect Ent-D to lose against any opponent she didn't immediately outclass. The Constitution-Class Enterprise, Defiant, and even the oft maligned Voyager won extended fights more than the Ent-D, and against equal or more powerful opponents far more. Part of this can be blamed on special effects of the time, as well as the cliché of how starship battles were expected to go - before Babylon 5, starship battles that weren't flat out animated were done by having a 3 or 4 foot model being filmed by a large camera that swung around at various predetermined angles, not leaving much room for freedom of movement to film the ship moving in full 3D. However a lot of this can be blamed on the fact that most Federation Captains in ST aren't portrayed as being very good at starship fighting, whatever their [[InformedAbility Informed Abilities]] may be. Picard is supposed to be a tactical genius, but when faced with equal opponents, he will often just fire a phaser bank or two, a spread of photon torpedoes, and get the stuffing knocked out of him until the plot intervenes. In Yesterday's Enterprise, when faced with a group of Klingon Birds of Prey that are effectively trying to stop history from unfolding as it should, Picard's brilliant maneuver is to fire 4 or so photon torpedoes at one of the ships, and get the stuffing knocked out of him until the plot intervenes. Any other non Federation modern spaceship captain (with the exception of Sisko who was an exception in that he was an effective fighter against superior odds) would have just fired at the enemy until they weren't there anymore. So yeah, Galaxy Classes suck, but they get a lot of help doing so.
*** I would add to this that it was also a different time. The Galaxy Class wasn't a 'warship' and it's specifically stated in [=DS9=] that Starfleet doesn't build warships and that the Defiant was an exception due to the Borg. TNG is a time of peace/alliance with the Klingons and truce with the Cardassians and Romulans. The Starfleet of TOS was a lot more martially focused because of the active Klingon threat of the time. Later TNG with the Borg and [=DS9=] as a whole show that Starfleet was in a place of defense complacency when the Galaxy Class was built.
** Finally ended in ''Series/StarTrekDeepSpaceNine''. After the ''Odyssey'' gets blown away Starfleet apparently decides "Enough is enough". They stop sending single [=GCSs=] in unsupported and start using them as heavy battleships at the core of multi-starship formations, and the [=GCSs=] start winning. You haven't lived until you've seen the triumphantly contemptuous way the USS ''Venture'' blows away a Cardassian orbital weapons platform in "Tears of the Prophets".
* In "A Matter of Time", a 22nd century inventor with a stolen time machine cons his way onto the ''Enterprise'', tries to steal some future tech he can reverse-engineer, and gets caught. This isn't the stupid part. The stupid part is that they allowed his stolen time travel pod to ''return to the 22nd century''. They solved one problem only to potentially create another. If they weren't being idiots in this scene, the proper thing would have been to send Data or Worf back with him, have him immediately return to the 24th century, then sent the pod back to its proper time.
** Maybe that's the real reason there were so many {{continuity snarl}}s in ''Series/StarTrekEnterprise''. A bunch of primitive yokels got their hands on a time machine and proceeded to screw up every part of history they touched.
* Then there's the episode ''The Price''. An alien species finds a wormhole in their territory, decides to auction it off for sale to one of the great space powers. In the episode, it's explicitly stated by Picard that the aliens they're negoitating with don't have manned space travel. So why are they doing business with them again? Isn't this breaking the Prime Directive?
** You can have warp capability and not have access to manned space travel. They may have a fleet of probes.
** It's always been this troper's interpretation that the "no contacting a pre-warp civilization" part of the prime directive is waived very, very often by starfleet command. It never seems to apply if there's already been contact made by others, or if they made contact with Starfleet, which in no way presupposes warp travel. My spin on episodes where the characters make a moral issue out of it is that they're just trying to keep up appearances, or that they're in the minority in Starfleet in attaching that much weight to it.
** The Prime Directive never applies when it would inconvenience or threaten the Federation. In TOS: "Errand of Mercy", Kirk makes contact with a seemingly ''Medieval'' society because the Federation wants to use their planet as a base in a mounting war with the Klingons. In TNG: "Angel One", the titular planet supposedly has "20th Century" technology, but had in fact been visited more than ''60 years'' before the ''Enterprise-D'' showed up. But they are conveniently situated near the Romulan Neutral Zone, and so the Federation hopes to ''bring them in as a member''! In VOY: "The Omega Directive", Janeway falls back on the titular regulation to kick down the door of a species that is technically "pre-warp", but clearly has superior knowledge of particle physics than the Federation or the '''Borg''' and take away the dangerous product of their R&D without any negotiation or compensation!
* Prime Directive episodes seem to breed Wallbanger moments like a momma Tribble makes young, and the episode "Pen Pals" is no exception. This episode essentially codified that Starfleet will make no exception to its nonintervention policy when a pre-warp society faces disaster. Now this policy may make sense when the disaster does not threaten the survival of the species, or if it is self-inflicted (say, a nuclear war). But it makes absolutely no sense when a pre-warp society is threatened by a cataclysmic ''natural'' disaster that is not of their making, which is what "Pen Pals" is about. Picard seems ready to default to leaving an entire civilization to die because of a half-baked assumption in a cosmic intelligent design before Data effectively forces his hand. This ghoulish interpretation of nonintervention would later be taken to its rancid logical extreme in the ''Enterprise'' episode "Dear Doctor", widely seen as the lowest point in all of Trek and which has a Wallbanger entry of its own.
** This is made worse by the fact that it is very much a DependingOnTheWriter issue. In the episodes "Déjà Q" and "True Q", the B-plots revolve around saving technologically-advanced civilizations from extinction-level events. In the first case it is natural (the planet's moon is dropping out of orbit) and the second it is the planet's native's own fault for massively over-polluting their world! This is meant to contrast the selfish nature of the omnipotent Q. But it raises a major moral question, as civilizations that seem to be advanced enough that they ''should'' reasonably be expected to do something to save themselves, or evacuate their populations from their doomed homeworlds, are given unconditional assistance by Starfleet. In contrast, less advanced civilizations are expected to fend for themselves. It's like the core ideal shifts from Gene Roddenberry to Ayn Rand!
