* SugarWiki/AwesomeMusic: The main theme (and closing credits theme) are among the best of the animated DCU films.
* CompleteMonster: Owlman was already a criminal and founding member of the Crime Syndicate of America. Upon discovering the existence of the multiverse, Owlman became enraged by the fact that, with every choice a person makes, they literally create another world in which they made the opposite choice. Determined that his choices had to affect not only his world, but all existence, Owlman journeyed to Earth-Prime, the Earth that supported the existence of all other Earths, planning to [[OmnicidalManiac destroy all reality in a fit of existential angst.]] About as selfish as they come, Owlman was reviled [[EvenEvilHasStandards even by his compatriots in the CSA]].
%%Do NOT add any other entries without going to the cleanup thread first.
* EnsembleDarkhorse: Ah, Jester. WeHardlyKnewYe.
* EvilIsSexy: Superwoman and Model Citizen.
* FanonDiscontinuity: Inverted, if that makes sense; there are people who still place this in the DCAU despite the final product not being part of it. Of course, most of the developments in in the film still fit in that continuity very well, which makes more sense with most of the story intact from the unmade version.
* FoeYay: Good Lord, Batman and Superwoman. From their introduction until he manages to get the best of her is just one big {{UST}}-filled FoeYay scene. She even ''kisses'' him and offers to keep him as a pet. [[MemeticMolester Batman needs an adult.]]
* GeniusBonus: Owlman naming his [[EarthShatteringKaboom planet buster]] the [[http://en.wikipedia.org/wiki/Q.E.D QED]]
* InternetBackdraft:
** There's complaints over the idea that [[TheyChangedItNowItSucks Superwoman may be the evil amalgam of Mary Marvel instead of Wonder Woman.]] Comic Mythos really is SeriousBusiness.
** This is in part because it reminds the fanbase of the ''ComicBook/CountdownToFinalCrisis'' series where the regular Mary Marvel turned evil, which wasn't very well-received.
** It's also because if this Superwoman is Mary Marvel, that means that Owlman is [[{{Squick}} in a relationship]] with a ''teenager.''
* NightmareFuel: An evil {{Expy}} Of Batman? Pretty scary. An evil Expy of Batman voiced in a CreepyMonotone by Creator/JamesWoods? ''Really'' scary. An evil Expy of Batman nihilistic enough to unmake reality in aformentioned fit of extistential angst? Long story short, Owlman is quite a terrifying villain.
* OneSceneWonder:
** Batman's reinforcements on the satellite, with Aquaman being chief among them.
** ComicBook/{{Firestorm}}, who shows hints of being a DeadpanSnarker in his limited screwntime.
** The Jester, aka ComicBook/TheJoker's GoodCounterpart. Goes out with a bang, yet he only appears in the first few minutes.
* RomanticPlotTumor: The main story is about the league trying to liberate an alternate earth from an evil Justice League, but a good deal of time is spent developing a romance between Rose Wilson-2 and ComicBook/MartianManhunter. Had the story taken place in the Franchise/{{DCAU}} (as originally intended), it would have probably been valuable character development for him (indeed, in the actual DCAU, J'onn is PutOnABus to go on a soul-search to learn how to connect to humans at about where the movie would've been), but it's pointless when that's taken out of the equation.
* {{Squick}}: As Superwoman is a copy of Mary Marvel rather than Wonder Woman, this implies that she's in her late teens at the oldest. Either she's good at keeping secrets, or Owlman is a creepy weirdo. Moreso, at least. Also, when she casually reaches over and snaps one of Batman's ribs like she was breaking a twig, while ''outright stating'' that she gets a sexual thrill from it and likes to do it to ''all'' her lovers.
* StrangledByTheRedString: Rose Wilson has a crush on ComicBook/MartianManhunter. The Martian inadvertently discovers they're "attuned" when he accidentally reads her thoughts (something he'd never do by accident with a non-attuned person). He then Mind Melds with her so that they can get to know each other instantly and fall completely in love.
* TheyWastedAPerfectlyGoodCharacter: The Jester. Granted, he ''did'' have an [[DyingMomentOfAwesome awesome death scene]], but there are a lot of viewers who would've liked to see him go to the other universe with Lex.
* TheyWastedAPerfectlyGoodPlot: There's a lot of potential to be had watching from Superman interact with a noble, heroic version of Lex Luthor. But, aside from beating up Ultraman once, the alternate Lex more-or-less fades from the plot after bringing the heroes over, and he and Superman barely share two scenes.
