Complete Monster: Queen Bansheera is probably the worst boss in the history of the entire franchise. The queen of the demons, Bansheera returns to power by callously sucking the life out of one and forces Diabolico, her once loyal general, to open fire on his enemies without caring that her most loyal minion Loki, whose only desire has ever been to serve her, is caught in the blast and dies. Diabolico has his mind forcibly erased to serve as her pawn. Her own son, Olympius fares little better, and Bansheera once ordered him abandoned to his fate while laughing. He is forced to fight alongside a brainwashed Diabolico, and his death provokes no feeling in her whatsoever. In addition, Bansheera attempts to open a gateway to the demon realm, allowing all demon-kind to pour out and overwhelm humanity.
Ensemble Darkhorse: Ryan. While it's per the course with The Sixth Ranger, he is special in that he is the first Ranger to not have a pre-existing Sentai counterpart. He was so popular, that he was near the finals in a Ranger popularity poll, there was a demand for a Titanium Ranger Key, and some have complained that he wasn't going to be in Super Megaforce.note Rhett Fisher, Ryan's actor, was invited at first, but was later uninvited for budget reasons.
There is also the theory that says that the Rescue Zords were built from or reverse-engineered from the wrecks of the original Rescue Zords. Supposedly, this was the writers' original plan, but nothing's ever been outright confirmed on the matter.
Fan-Preferred Couple: Carter and Dana. Some episodes suggest they are interested in each other and a flashback in "The Last Ranger" reveals the two are dating.
"Funny Aneurysm" Moment: Nearly every human-sized monster gets blown up, and Carter says "Mission Accomplished", except that Jinxer always brings them back to life and megazord-sized. Saying "Mission Accomplished" except the threat is far from over, and has actually gotten worse? Seems like President Bush's infamous 2003 moment, but Lightspeed Rescue aired in 2000.
A major villain from a previous series is revived for a crossover and teams up with a villain exclusively created for that crossover, and when they come back, they are wearing a mask. Am I talking about Trakeena in Trakeena's Revenge teaming up with Triskill, or Ryoma Sengoku in Movie War Full Throttle teaming up with Megahex?
If you've watched the source material, any episode that suggests Carter and Dana are interested in one another, since their sentai counterparts are siblingsnote unlike Power Rangers Megaforce, where something similar happened, this would have happened regardless of which rangers Carter and Dana were, since in GoGoV, the entire team was a family.
Moral Event Horizon: Queen Bansheera does truly horrible things. She crosses the line when Olympius, her son, ends up stuck in the local equivalent of Hell; she opts to leave him there for being useless enough to get stuck there in the first place, and seems to take perverse pleasure in doing it, too.
Narm: Just about all of Vypra's dialogue would make any viewer laugh because of the incredibly bad acting.
Narm Charm: Blowing up a city with explosive feathers is... okay, it's pretty cheesy (even for Power Rangers). But the episode does its darn best to make it pretty believable.
Never Live It Down: No matter how many badass moments Carter had, two things stick out amongst fans: using his blasters and his dull personality. For the former, this criticism was unfair in "Forever Red", where the Cogs he faced used blasters as well, and he was smart enough to use his own weapon.
Considering the Rangers function as a milita, the shoot first mentality made sense.
The Curse of the Cobra, with Ryan suffering and writhing in pain every time he morphs, with it coming incredibly close to outright killing him.
The end of the episode where Diabolico dies. From Impus turning into a cocoon onward, to Queen Bansheera announcing herself to the Rangers... not helping is the legitimately good score the series has makes the cocoon descending from the sky actually unnerving. (Not helping is that on the VHS release, the cliffhanger of Impus' cocoon hovering over the city was a cliffhanger).
Queen Banshera's deformed form is not a pretty sight.
Mis-blamed: In regards to Carter, it's not his fault that his Sentai counterpart didn't use a sword. There weren't even any swords in the arsenal or toyline! Go Red used a gun, so the Red Lightspeed Ranger uses a gun.
So Okay, It's Average: Of all the Power Rangers seasons, this is probably the one which gets the most indifferent reaction from the fanbase. Very few actively dislike it in the same way that they do Turbo, Operation Overdrive or Samurai, but at the same time you likely won't find a single fan who considers it to be the show's best season.
Surprisingly Similar Stories: The 2005 movie "Stealth" was the bigger version of the "Cyborg Rangers" episode of this season. Robots are improved humans until they get hit by lightning and go nuts and the humans can't be improved on after all.
They Wasted a Perfectly Good Character: Vypra, despite her actress's performance, could have easily been the most interesting villain of the season. The past two seasons had the human looking female villain either reformed (Astronema) or just a more complex character (Trakeena). Vypra... is neither. Her most notable aspect was acting as surrogate mother/big sister to Impus, but that goes away when he becomes Olympius. They could easily made her something else, a seductress, having a thing for one of the rangers or The Starscream, instead she's just a henchwoman.
They Wasted a Perfectly Good Plot: Dana is the Captain's daughter, she is the most knowledgeable of Lightspeed of the 5 Rangers. She is not chosen to be leader. Never once does the show actually address this issue or Dana feeling resentment or hurt. Mind you, Power Rangers Wild Force and Power Rangers S.P.D. would make the "Ranger more equipped to be leader, but isn't" into character plot points.
Not to mention, thanks to Linkara's review both Carter and the series' image overall is improved (though this started happening BEFORE Linkara's review). He points out how Carter Grayson may be dull but was a badass firefighter before being a ranger. While many fans disliked that Carter went for his guns first, Linkara loved that aspect because it made him one of the more Combat Pragmatist red rangers.
Visual Effects of Awesome: The Aquabase which was heavily detailed and built with an acutal aquarium to simulate the underwater environment.
Also, their transformation sequence is pretty awesome in and of itself. It is probably one of the more elaborate sequences on the show to date and it shows very well.
What an Idiot: The receptionist from the Crossover episode who told a little girl "there's no such thing as monsters". As Linkara says, she is the dumbest person in the history of the entire franchise.
WTH, Casting Agency?: Koko Kashmere from the filler episode towards the end? She was played by Ruta Lee, famous as the model and dice roller from the original NBC run of High Rollers.
