Fueled largely by DC, who shunted Hal Jordan and the rest of the Corps out of the spotlight to make way for Kyle Rayner, who himself was counter-shunted when Hal Jordan returned and Kyle became a supporting character.
To say nothing of John Stewart's fanbase, largely earned from his role as the Green Lantern for the DCAU.
The Green Lantern books not being affected by the New 52, at least less so than other books (Alan Scott, the original Green Lantern, now no longer exists on Earth 1, which DC keeps pushing as the main/primary universe, which seriously alters the back story of Kyle Rayner since Alan was his mentor, and had his sexual orientation altered for what many believed was a cheap publicity stunt when he was shunted to Earth 2) to the point that the only costume change to Carol Ferris' Star Sapphire costume would be overhauled a year after the reboot and a slight variation to Hal's uniform from before the reboot. Whilst some are happy that nothing changed, others aren't happy that literally every other character in DC's roster that wasn't directly tied to the Lanterns underwent some sort of overhaul & every book had a creative team shake-up, whilst Johns got to stay on Green Lantern & keep all of his work in continuity.
Mongul II is a case of Overlord Jr. at its worst, and has dedicated his life to aping and surpassing his equally unpleasant father, Mongul I. During his first appearance in Green Lantern, Mongul II used the Black Mercy plants to trap Hal Jordan and Oliver Queen in a fantasy world; he subsequently murdered his sister, Mongal, and kept her corpse as a trophy. When Mongul II really comes into his own, however, is after gaining a Sinestro Corps Ring (by murdering its owner). Taking control of the Black Mercy homeworld, Mongul II uses his ring to alter the genetics of the Black Mercies so that they will trap their victims in their worst nightmares, instead of their ideal fantasies. He coerces the benevolent Mother Mercy into aiding him by threatening to make her eat her own children if she does not. Defeated by the Green Lanterns, Mongul II escapes from prison, seizes control of the Sinestro Corps by killing anybody who disagrees with him (or even annoys him in the slightest), rips out Arkillo's tongue, and overruns the planet Daxam, slaughtering or enslaving the population. Beaten off by Sodam Yat and Arisia, Mongul II later arrives on Korugar, and is in the process of having the citizenry strung up along the streets when his reign is finally halted by the return of Sinestro.
Krona's arrogance led to the creation of the multiverse & antimatter universe and/or evilnote other versions involve entropy & the "universe being born old", but if that was just a result of him holding the Idiot Ball, the stuff he did after that put him well across the Moral Event Horizon. War of the Green Lanterns retconned him into being the one who was behind the Manhunter's annihilating a sector, but we had seem him do far, far worse long before we learnt that, and at the absolute apex of his villainy he was callously destroying entire universes because he thought he could do better. The most chilling thing about him is that he can commit mass murder on a multiversal scale with zero compunction, and believe he was completely in the right to do so.
Continuity Lock-Out: There are about a half a dozen or more series running with the storyline weaving in and out of each one at random. The storyline that started with Series A will continue along its course into Series B, C, D and friggin' Z and by the time it veers back into Series A the very next issue won't pick up where the last one left off. For a random example: New Guardians issue 12 ended with the "New Guardians" parting ways with Kyle all alone. Issue 13 rolls around and Kyle is suddenly back on Earth, training with Atrocitus and Carol, having at some point acquired the ability to channel the powers of all seven colors without the need for a respective ring.
Larfleeze will steal the coat off your back and claim it was his all along.
And Dex-Starr will puke explosive blood all over your new shag carpet unless you buy him the right catfood.
Salaak, with the whole "robot catgirl threesome" thing.
Creator's Pet: Dwayne McDuffie had Green Lantern John Stewart, though this was largely part of self-fulfilling prophecy; a lot of fans didn't like Stewart for the way he leapfrogged Kyle Rayner (previously established in the animated canon) and longtime comic GL Hal Jordan to be the Justice League Unlimited Green Lantern. This led to McDuffie (a black creator who was quite vocal on what he felt was racism within the TV and comic industry, and who had inherited Stewart on the cartoon from the previous showrunner) making some comments equating hatred of Stewart as racism, which led to the widespread notion that Stewart was McDuffie's pet character.
One could argue that the Green Lantern has been a source of shilling the creator's pet since the 90s. Start with Kyle Rayner replacing Hal Jordan and the writers trying to shill him to win over the fan base disgusted by Hal's Face-Heel Turn in Emerald Twilight. Fast forward 10 years, and a number of those fans are now writers/editors for DC, and they promptly retcon the heel turn and restore Hal to being GL Numero Uno - and now must shill him to the fan base who grew up with Kyle and are upset with him getting booted down - and John Stewart as described above.
Interestingly, a few writers did make Kyle work for his place in the DC Universe. A number of writers, like Grant Morrison, had characters like Wally West look down on the rookie Lantern for just being there and made to bust his chops to earn his place in the greater scheme of things.
Geoff John's Hal Jordan can come off as this at times. He's the Greatest of Green Lanterns, and constantly told so, even though the bulk of his accomplishments are only achieved through dumb luck, he can be as much a Jerk Ass as Guy Gardner, yet rarely be called on it, because the Parallax fiasco was retconned into being him possessed by a giant bug, that was apparently inhabiting him for years without any real change to his personality until he went nuts, his record is now spotless and he's somehow so important to the Universe that he's been able to sample the entire Emotional Spectrum, just because he's Hal Jordan.
Ensemble Darkhorse: Many characters qualify, but DC tends to treat Guy Gardner as the black sheep of the Earth born Green Lanterns. Other examples are Kilowog, Ch'p, G'nort, Dex-Starr, Larfleeze, and Mogo.
Arkillo has fast become one as well thanks in no small part to the massive amount of character development he received.
Ethnic Scrappy: The Silver AgeGreen Lantern Hal Jordan had an Inuit sidekick called Pieface who served as his mechanic. Today, he is strictly called Tom Kalmaku and depicted with respect as an engineer.
In a retelling of Hal's origin, the "Pieface" nickname is used by a Jerkass rival pilot.
Fair for Its Day: The characterization of Tom "Pieface" Kalmaku in the 60s. One one hand, the character was a minority in a highly skilled position at Ferris Air, spoke excellent English, and became Hal Jordan's close friend and confidant. On the other hand, his nickname was "Pieface" (as in Eskimo Pie), and he liked to exclaim "great fish hooks!" when shocked. It should be noted that Hal always treated him with respect.
Genius Bonus: Sinestro is usually depicted as wearing his ring on his left hand. For those unfamiliar with Italian (or Latin), the masculine for "sinister" is "sinistro", which means on the left hand, but also wrong, perverse, unfavorable, etc etc etc.
Flash once had a villain called the Rainbow Raider, who could make hard-light rainbows and induce emotions in people by coloring them. He'd fit right in with the emotional spectrum retcon, but sadly, he's dead, so the only time he's been used since then was as yet another Black Lantern.
There was an episode of Aladdin The Animated Series which featured multicoloured emotion-inducing rings - including a yellow one which made you cowardly, an orange one that made you self-destructively greedy and a red one which made you suicidally angry - well before the Red and Orange Lanterns, and quite probably the modern Sinestro Corps, came onto the scene. (Though to be fair, the association of cowardice with yellow and rage with red are extremely old, though the orange=greed thing is kind of strange, since orange has few cultural connotations beyond "Dutch.")
In the very first comic featuring the Green Lantern (then the first incarnation of Alan Scott, when the green light was connected to chinese folklore rather than the Emotional Spectrum), the Lantern's green light was reffered to as "queer". Flash forward to 2012...
In Rebirth, Ganthet tells Kyle that "hope is meaningless against fear". The guardian would later go on to co-found the corps channeling the power of hope itself. Depending on how much Johns planned in advance this may or may not be intentional.
Ho Yay: Guy and Kyle's close relationship is interpreted this way pretty often, even by non-fangirls, especially after Kyle died and Guy was so heartbroken at losing his friend that he attracted a Red ring and went on a rampage. Seconds before this happened, he could even be seen holding Kyle's hand and crying.
Les Yay: So much of it between Bleez and Fatality. Actually, considering her unwillingness to ever take a suitor, it isn't unreasonable to assume Bleez may actually swing that way. Fatality is one of the only beings Bleez has willingly shown her face to.
Green Lantern and Flash always tend to evoke this, no matter which Flash or Lantern it is. Alan/Jay, Hal/Barry, Wally/Kyle and Wally/John in the DCAU, etc. Bart and Guy are the only two who don't have this with anyone from the other side of the dynamic, mostly because Bart is too busy having it with Robin and Superboy and Guy is too busy having it with Kyle.
Jerkass Woobie: According to the Christmas comic, Larfleeze, as it's revealed he misses his family above everything.
Like You Would Really Do It: Killing Hal & Sinestro in the 2012 Annual... Or rather, keeping them dead beyond the Rise of the Third Army event, with most fans expecting the characters to return during the latter stages of the event. They were right on Sinestro, Hal had to wait a few months longer.
Way before that, Sinestro was able to take control of Space Sector 3600 after telling the sector 1,001 tales to prove that the Guardians were weak, and together, they were able to destroy countless galaxies and destroyed Kilowog's rebuilt planet, until they were stopped by the Corps.
Mis-blamed: When McDuffie took over the Justice League of America comic, he was told to use John instead of Hal as the Justice League of America's Green Lantern on orders from above (partly because Hal was being given HIS JLA TEAM!). Sadly for McDuffie, fandom took the change badly, not helped in the least by the fact that Hal's JLA spin-off was delayed and reduced to a mini-series when it became apparent that James Robinson's artist was never going to get the book done on time. This lead to Hal returning to the title until his book was ready, followed by John's re-instatment just long enough for him to be bounced again and replaced with Hal until he was quickly replaced with Jade when they needed a book to focus on her Brightest Day storyline. The entire process was made progressively worse and worse by Executive Meddling, in case you couldn't tell. And when McDuffie had the gall to describe this and the other creative difficulties on his forum (without assigning blame or complaining), DC responded by firing him.
Black Hand killing his family as a prologue to the Blackest Night, simply because Death told him too. Given Flashpoint and Green Lantern v5 #11 showed us that simply dying is enough to "rise", it counts.
My Real Daddy: The entirety of the modern Green Lantern mythos has Geoff Johns, but particularly Hal Jordan and Sinestro. For many readers, he is the Green Lantern writer.
Half the crap drawn by Ethan Van Sciver. Especially his version of Parallax-possessed heroes.
The entire Sinestro Corps, in a literal sense.
Parallax. Being an Emotion Eater, it's a primary weapon. Plus his appearance looks pretty demonic.
Kryb. Her method of instilling fear? She kills parents and steals their infant children for herself.
Even worse, she genuinely loves the children in question. Truly and sincerely, with all her heart. To the point that a Star Sapphire can use her love as a tether to track the children in question. High Octane Nightmare Fuel should simply not be crossed with woobiedom!
Romat-Ru. He killed thousands of children.
The Third Army - Hideous, emotionless monsters designed by the Guardians to replace the Green Lantern Corps & thus are able to withstand everything a Green Lantern Ring can throw at them and effortlessly break through any barriers they throw up. Oh, and rather than kill you, they instead forcibly turn you into one of them, and you'll be aware of what's happening when they do so.
Black Hand returns (again) for his Villains Month issue and once more causes a (so far local and non-Black Lantern) Zombie Apocalypse. This is Nightmare Fuel enough, but when he runs into policemen who keep mowing down his zombies, he reanimates dead viruses inside one of the cops, quickly killing and reanimating him from the inside. Yikes. As if that's not enough, at the end he rips off his own hand and replaces it with that of (zombie) Martin Jordan, just so he can kill Hal with his father's hand when they next meet.
It's an FAQ where casual viewers confuse Justice League's Green Lantern John Stewart with all others and ask "Isn't Green Lantern black?," even though Hal first appeared a dozen years before John.
Modern GL readers are familiar with the many Corps and the emotional spectrum, but the Sinestro Corps was not the original opposite number of the Green Lantern Corps. That honor goes to the anti-matter ring wielding Anti-GL corps, from GL #150.
The Star Sapphire is generally known as a Green Lantern adversary, but a Star Sapphire first appeared as a Golden Age Flash enemy in All-Flash #32, December 1946. This Star Sapphire's identity was unknown, but she would later be retconned as a failed and exiled queen of the Zamarons.
Protection from Editors: The Green Lantern books under Geoff Johns are one of the two things to enter the New 52 unscathed, the other being Grant Morrison's Batman run. Whilst Morrison's Batman Inc. continued the plot he was writing before Flashpoint but had everyone spontaneously change costumes, the Green Lantern books don't even do that & just carry on as they were before the reboot. This can be attributed to Johns being the Chief Creative Officer of DC Comics, essentially the No. 3 guy at the company after co-publishers Dan DiDio & Jim Lee.
Replacement Scrappy: Kyle Rayner to Hal Jordan fans. Hal Jordan to Kyle Rayner fans. Both to fans who only know about Green Lantern from the Justice League cartoons.
Grant Morrison asked Ron Marz "How would Rayner work in a team book as opposed to a solo one?" The characters were very similar, and Kyle's era was a best seller until Ron Marz left the book. and by that time Morrison was no longer writing JLA. It would be BETTER to say he became a Scrappy during the Judd Winick / Ben Raab Era and Ron Marz and Geoff Johns rescued him from the Scrappy Heap. The only people to whom he was ever a scrappy were die-hard Hal Jordan fans. Kyle Rayner was the star of the Green Lantern book for ten years, and thus had a generation of his own fans who couldn't care less about Hal Jordan and thus never saw him as The Scrappy in the first place. To those fans, it was Hal Jordan, and not Kyle Rayner, who was Rescued from the Scrappy Heap.
Anyone who was around for the time of Emerald Twilight can say that Kyle was very much a Scrappy when he was first introduced. Morrison's JLA run went a long way towards establishing him as an interesting character.
Guess it's both worked for Kyle. For a number of readers who stayed with the GL title after Emerald Twilight it was the unfortunately-now-infamous Stuffed into the Fridge moment that brought out the humanity in Kyle for the readers to see and relate. Morrison's take on him at first can tend to be Narmy, with Kyle uttering slang words like "dude" and "man" (which Marz very much averted in the GL comic), but the chemistry he gave Kyle with the other heroes in the JLA, particularly withWally West, and the exposure he gave him there has made Kyle much more acceptable to those who don't read the GL comic.
Rooting for the Empire: Sinestro has been getting some attention in this manner, mainly due to him being a very charismatic villain and his arguments against the Guardians being too involved with their mysteries and prophecies to do an effective job policing the cosmos.
Tear Jerker: When the Butcher looks into Atrocitus' mind to find out what makes him angry, we see a flashback him with his daughter, telling her they'll be a family forever, followed by one when the Manhunters attacked.
Also, the aftermath of The death of Mogo.
The death of Sayd. As she holds off the Third Army alone, she pleads to the fleeing Lanterns to tell Ganthet she loved him. Thankfully she & Ganthet are reunited & happy in the end.
What an Idiot: Hey Mongul—Sinestro created the friggin' rings; he'd have a manual override in case of an attempted coup!
The Woobie: Holy shit did Karu-Sil have a horrifying childhood.
Critical Backlash: If you read some online reviews like at Amazon.com, a lot of people are saying "I liked the movie, I don't get why the critics absolutely hated it..." making this a strange example of having both Hype Backlash and Critical Backlash.
Moral Event Horizon: When Hector Hammond turns two giant flamethrowers on a US Senator and roasts him alive. To make it worse, the senator is his father. To be fair, his father was an Asshole Victim, and clearly a bad parent. Not that this justifies killing him, but Hammond's moral horizon was probably less killing / trying to kill him than endangering and killing a whole bunch of innocent people (and less innocent, but still not evil, government scientists and agents) in order to. Also, Hammond's not in total control of himself.
One-Scene Wonder: Kilowog in the film. In fact, most anything involving the GL Corps in the film.
Some Anvils Need to Be Dropped: Regardless of one's opinion on the film, it does deliver a good message on how courage is not about feeling no fear, but overcoming it. Insisting that one has no fear only makes it stronger, but accepting it allows one to not let it control them.
Special Effects Failure: Conspicuous CG is invoked with the Lantern uniform and constructs. They're alien energy objects; they shouldn't look wholly realistic. That said, some of the non-alien effects have no such excuse.
Also, all the introductory scenes look ridiculously fake, and there are plenty of times during Hal's training on Oa where it's inescapably obvious that you're watching Ryan Reynold's head in front of a green screen. Plus, every scene with Sinestro (or any of the aliens, actually).
Tainted by the Preview: Many fans were not encouraged by the trailers, partly due to the special effects being underwhelming and also due to the "Iron Man" vibe.
This was actually acknowledged by some people in the industry, the first teaser trailer was very underwhelming because they had very little completed special effects to work with. Thus the initial impression made it seem more like a sitcom than a genuine superhero movie. While the later trailers were much more impressive, it came across as too little too late.
Probably the biggest problem with the trailers though is just how much they spoiled several plot points, including the fate of one of the villains.
Tough Act to Follow: Not necessarily a bad movie, but being the first major DC film after The Dark Knight, Green Lantern had a lot to live up to comparatively speaking. The comparison isn't exactly fair in the first place as although being "superhero" movies within that spectrum they are in wildly different genres. The Dark Knight is a crime/vigilante drama while Green Lantern is a Sci-fi Space Opera. Getting to theaters behind Thor didn't help things either.
Uncanny Valley: The "painted" on mask and CGI suit never quite looked right to a lot of viewers. Although considering the uniforms are energy constructs, this may have been a deliberate design choice. The glowing blue eyes as part of Hal's "disguise" are perhaps the worst part.
