* AlternativeCharacterInterpretation: JohnDiMaggio's version of SelfDemonstrating/TheJoker is much more brutal than other portrayals.
* BetterThanCanon: An amazing case. Not only do many fans like this version of the story better than in the comics, Judd Winick, who wrote both the original comics story and this movie, [[FixFic considers the movie the better version]].
* CompleteMonster: SelfDemonstrating/TheJoker is once again presented as an AxCrazy psychopath. He beats Batman's young sidekick Jason Todd with a crowbar, leaves him broken and battered in a warehouse and then proceeds to blow up the warehouse. Later in the film, Joker kills four of Black Mask's mooks for no reason, after Black Mask ([[EvenEvilHasStandards very reluctantly]]) [[UngratefulBastard freed Joker from Arkham]]. Joker then attempts to kill both the Red Hood's and Black Mask's gangs by covering them with gasoline and using a lighter to try to set them on fire. Also throughout the movie, Joker taunts Batman about Jason's death.
* CounterpartComparison: A ''lot'' of people noted Red Hood's resemblance to SelfDemonstrating/{{Deadpool}} when the first trailers went online. The similarities are even more marked in the actual film, where the character behaves near-identically to Deadpool in the latter's earlier appearances.
* EnsembleDarkhorse: In ''spades''. There's Red Hood, Joker, Nightwing, Black Mask, the Fearsome Hand of Four, and Ms. Li.
* FoeYay: The Joker interrupting Batman's TearJerker speech by saying "aw, so you ''do'' think about me!" In the Joker's typically disturbing fashion, he says this while Batman is saying that [[spoiler:not a day goes by where he doesn't think about killing the Joker]].
* FridgeBrilliance: Nightwing and Batman visit Joker in Arkham to see whether he was related to the Red Hood in any way, which he is not. [[spoiler: However, his actions caused Jason Todd's death and subsequent transformation into Red Hood after his resurrection]], so in a way the Joker was linked to Red Hood in more ways than one.
* SugarWiki/HeReallyCanAct:
** Many a fan doubted that Creator/JohnDiMaggio could pull off the Joker, but once they actually saw the movie, they quickly changed their minds.
** Creator/JensenAckles as Jason raised some eyebrows, but he silenced everyone with a heartbreaking performance, especially in his final scene.
* IdiotPlot: Some accuse the film of bordering on this, mainly due to Black Mask hiring the Joker.
* ItWasHisSled: [[spoiler:A resurrected Jason Todd, the second Robin, is the Red Hood.]] For comic book fans, this is common knowledge and the film barely tries to treat it as a genuine mystery for long.
* JerkassWoobie:
** [[spoiler: Jason Todd/Robin II/Red Hood.]]
** Ra's al Ghul. Despite his being a ruthless supervillain who, as Batman says, has never shied away from shedding blood, his deep remorse and sorrow over [[spoiler:Jason's fate, resurrection, and subsequent rampage]] are clearly heartfelt and genuine.
* [[LikeYouWouldReallyDoIt Like He Would Really Do It]]: Red Hood tossing a gun to Batman and telling him to shoot Joker.
* MagnificentBastard: See BatmanGambit.
* MemeticMutation: Variations of this piece of dialogue, swapping out Batman, Jason and Joker for other characters/parties:
--> '''Jason Todd:''' Bruce, I forgive you for not saving me. But why, why on God's Earth...is he [Joker] still alive?!
* MoralEventHorizon: The Joker crosses his in the film's opening scene, as he savagely beats Jason, then leaves him to die.
** In-universe, Batman believes that killing the Joker, even after everything the latter has done, would be his, which is why he won't do it.
* NightmareFuel:
* OneSceneWonder: Creator/JasonIsaacs as Comicbook/RasAlGhul.
* StrawmanHasAPoint: Like in the comic, Red Hood raises a good point on the naivety behind the idea that someone like [[JokerImmunity the Joker can continue to walk the earth]] even though he'll continue to kill thousands.
** And the fact that it's a logical fallacy to say killing the Joker would make Batman accept killing any criminal, when Joker has been the one villain who has never shown ''any'' capability of possible redemption in any form, unlike the rest of the Rogues Gallery.
* WTHCastingAgency: Reactions to JohnDiMaggio's casting as Joker were... mixed, to say the least. The release of the character models featuring a somewhat burlier Joker eased concerns somewhat. And then the film was released and a lot of those who doubted he could pull off the role did a complete 180.
** Audiences were also skeptical of JensenAckles playing a lead character, as he had never done voice acting work prior to this film.
** And anyone other than Creator/KevinConroy as Batman raises suspicions. But BruceGreenwood did a good job, especially as a Batman who's supposed to be a little older than we normally see him.
