These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Green Lantern: The Animated Series
Alas, Poor Scrappy: LANOS, after he goes into warp and takes Anti-Monitor Aya with him. Even Hal seems sorry for him.
Hal and Kilowog in "Reboot". Their hostility against LANOS begins immediately, without context, and they're willing to replace his AI with Aya's when the latter is to be dissected. This winds up as a Double Standard since it sends the message that it's okay to trade one sapient entity for another so long as the other is a Replacement Scrappy.
Anti-Climax Boss: After the Anti-Monitor being built up as a genocidal, universe-crushing, unstoppable Big Bad from the moment he appeared onscreen, he's killed by a super-charged, emotionless Aya in a matter of seconds before she hijacks his body and takes over as Big Bad of the season.
Arc Fatigue: According to some reviewers, the "Dark Aya" storyline is slow to get moving and could've wrapped up sooner.
Awesome Music: The soundtrack overall is gorgeous, and the title theme sure makes for its short run time with a triumphant fanfare.
Complete Monster: Atrocitus, the Big Bad of the first half of the series, is dedicated to the destruction of the Green Lantern Corps, having many of them murdered by his Red Lantern followers. First showing his ruthlessness in ordering a colony world full of innocent civilians destroyed, Atrocitus later revealed he had destroyed worlds to fill survivors with rage and recruit them as Red Lanterns. Unlike his comics counterpart, a Tragic Villain at worst and an Anti-Hero at best, Atrocitus in the show delighted over the pain he caused innocents and took sadistic pleasure in his actions. Even though he himself had once lost a homeworld, he gloated over inflicting the same agony on others like Razer.
Even when his only appearance was a few seconds in a sizzle reel, fans adore Saint Walker. This became ever more apparent when he appeared in the show came off about seventeen times more badass then he's ever been in the comics while keeping his characterization completely intact.
Ch'p. Within seconds he proved himself capable of taking out Hal Jordan, despite said Lantern's greater experience and having gone toe-to-toe with Atrocitus. It also helps that he's a squirrel.
The Steam Lantern is getting a lot of love too.
Fan Dumb: Several fans considered the series ruined by complaining about the Red Lanterns not being bloodthirsty mindless berserkers like they were in the comic, forgetting that there have been many good superhero adaptations that took departures from the original comics, and that this would allow more Character Development.
Fanon: There's a creator-supported theory that Razer has white hair.
The thrill that the planet from the Steam universe feels when they see the stars again becomes this when the stars start going out in their new one too.
The hashtag for the Twitter storm for the episode "Dark Matter" was "#HeroesNeverDie". Aya does.
"Dark Matter" opens with a speech from Appa Ali Apsa giving a speech to the Green Lanterns, saying that these may be the very last orders he will give them. In light of the series' cancellation, this provides a bit of Reality Subtext.
Ho Yay: In "Lost Planet", Drusa comments on the perfection of the curvy Aya and even gives a Male Gaze to her. She even pretends to twist her leg to have her carry her to the ship (granted she was just hacking into the ship but all the signs were there).
Internet Backdraft: News that the show would be cancelled did NOT go over well. Giancarlo Volpe wasn't particularly happy about the decision either. Even worse is that the network had let them know this for a long time but had refused them permission to say this until it was publicly announced. The internet then tried rallying to get the show restored, seemingly failing.
To an extent, Larfleeze. Yes, he is a greedy jerk, but you can't help but feel sorry for him when you see him bursting in tears, crying to get his "shiny" back. Becomes even sadder in perspective when you realize this guy once fought toe-to-toe with Atrocitus.
Just Here for Godzilla: A large amount of people only watched the show for Razaya, and the fanbase often ignore the other characters in favour of them. It isn't helped by the fact that they were the only ones to get any significant character development.
Sinestro's plan for driving the creature out of its host body. He sets the Interceptor to decompress, depriving the ship of oxygen. The crew members who aren't possessed will be able to protect themselves with their rings' force shields. Razer ends up being the one possessed, and he nearly suffocates. We're treated to several seconds of him gasping for breath and even passing out for a few seconds.
To add a third point to that episode, Sinestro's Breaking Speech to the dying mindjumper, revealing that he broke the seal when he broke out and leaving it to die, his truly creepy exploitation of Loophole Abuse (he didn't kill him, he just didn't save him), and his utterly calm lie to the crew that he must have suffocated, and how convenient it is that he died. He may remain a good guy throughout the entire episode, but it's made very clear that when he becomes a villain, he will be terrifying.
Aya survived her brush with death by downloading into a disabled Manhunter. While it is good to see her alive, the mangled Manhunter/Aya form she comes back in is quite disturbing. She then shuts down her emotions and absorbs the entire power supply of the Interceptor before using it to kill the Anti-Monitor... then hooks up to his systems and become what appears to be the new Big Bad.
Strawman Has a Point: Kilowog's arguments against Aya being a Green Lantern. While many of them boil down to "she's a machine" and cannot qualifynote he doesn't bring up the Guardians having a say in it, but then again the Guardians are the poster children for counterproductive, that and in Season 2 the Science Director tried to have her disassembled.. However, some points, like her assuming a robotic form and leaving most/all the systems of the ship, hold water, like when she left it to the cargo captain, who accidentally detached the cables she was using to tow a ship, and he could have flown it into the black hole. Also, when Razer caused an explosion/virus, she could not see what he was doing to the ship's systems from her form, and only used an optic to see what he was doing it was a fake out, but if it wasn't they'd be stranded right behind Shard.
Tomar-Re could have become the Sixth Ranger of Hal's group, considering his role as a more by the book lantern and was more level headed than the others, instead he only appears in 3 episodes.
Additionally, when the whole Green Lantern Corps ends up fighting the Manhunters, we see neither Sinestro (who was in for one episode and that was it, we probably would have seen more had the series continued) nor Mogo (who had appeared before and probably was banned owing to Story Breaker Power).
Uncanny Valley: Aya's face/eyes may fall into this category, depending on the viewer.
Invoked when Aya inhabits a decaying Manhunter's body. Everything from her face to her very movements is extremely unsettling.
What an Idiot: Yeah, go on, Ragnar, kill a Green Lantern in order to become one. His ring will surely judge you worthy for that... Even worse is that Ragnar is a fan of the Green Lanterns (meaning he should know that), yet he only believes that brute strength and ambition makes the wearer worthy, if that was the case, it still wouldn't go to him. Furthermore, even if Ragnar found a way to overcome this, the Guardians would never allow a power ring to be hijacked like that and the villain would face as many Green Lanterns as it takes to confiscate it.
Sure, Scar. Trying to take on the Anti-Monitor single handedly will surely end well.
