History YMMV / BatmanNinja

* NarmCharm: Bane as a sumo wrestler. He looks ridiculous, but its so over the top its likable.

* NightmareFuel: Joker's appearance in this film is [[http://media.comicbook.com/2017/12/batman-ninja-joke-1062618-640x320.jpg especially frightening]].

* HilariousInHindsight: ''Anime/TheBigO'' has been described as "''WesternAnimation/BatmanTheAnimatedSeries'' as a HumongousMecha anime" and features a protagonist named Roger Smith. Nearly two decades later, a straightforward ''Batman'' anime appears and his English voice actor is Creator/RogerCraigSmith.

* HeartwarmingInHindsight: Most portrayals of Bruce's relationship with the Robins in later titles haven't been always that close, usually strained. Here, while lamenting the loss of the Batwing, the Batmobile, and the Batcycle, Bruce admits that alongside his mind and spirit, he warmly adds that he has all of them, Alfred and Selina included (in the [[https://youtu.be/08dHXfIprYE?t=38s English dub trailer]]).

** Likewise, Jason's red hood just looks ridiculous to some viewers.

* CantUnHearIt: Anime fans might recognize Joker's Japanese voice actor, Creator/WataruTakagi, as the same actor who played Okuyasu Nijimura in ''{{Manga/Jojos Bizarre Adventure Diamond Is Unbreakable}}''. Considering the film goes with one of the more sinister Joker portrayals, and Okuyasu is (for most of the series) a very sweet, dumb-but-likable best friend character, it makes Joker just that much more ''creepy''.
* HilariousInHindsight: Anime/TheBigO has been called as WesternAnimation/BatmanTheAnimatedSeries as a HumongousMecha anime and features a protagonist named Roger Smith. Nearly two decades later, a straightforward Batman anime appears and his English voice actor is Creator/RogerCraigSmith.

** The film also supports an impressive posse, all veterans to acclaimed anime projects: An animation studio, opening credits director, and composer who all worked on ''{{Manga/Jojos Bizarre Adventure}}'', the screenwriter for ''{{Anime/Gurren Lagann}}'' and ''{{Anime/Kill La Kill}}'', and character design and English-language screenwriting from the creator (and producers) of the ''{{Anime/Afro Samurai}}'' manga, series, and film. More than a few fans were drawn in simply by being fans of the creators' other work.

* JustHereForGodzilla: There are some people who only want to watch this solely for the fact that all four Robins are appearing at the same time.

** Other ''Animation/BatmanUnderTheRedHood'', Red Hood has always been ignored or turned into a PosthumousCharacter by animated adaptations of the Batman Mythos, making his addition to the main cast a pleasant surprise.

** Other ''Animation/BatmanUnderTheRedHood'', Red Hood has always been ignored or turned into a LegacyCharacter by animated adaptations of the Batman Mythos. So many people were pleasantly surprised when he was revealed to be part of the main cast.

* VisualEffectsOfAwesome: ''Batman Ninja'' is a very good looking movie, especially with the SceneryPorn.

* {{HSQ}}: How many reacted to seeing a Batman anime movie in general, and the sheer awesomeness of the first trailer.

** While Tim Drake has appeared in animated adaptations before, it's almost always as ComicBook/{{Robin}} even after he abandoned the identity. This is one of the only adaptations to feature him under his current identity, the '''Red''' Robin.
