History YMMV / BatmanNinja

* FridgeBrilliance: ''Why'' was Gorilla Grodd in this movie? Well, RuleOfCool is one reason certainly, but looking into it deeper there is another reason. Joker is clearly the movie's version of UsefulNotes/OdaNobunaga, he is even called by the same epitaph as him, ''Dairoukuten Maou''[[note]]the Demon King of the Sixth Heaven[[/note]]. Nobunaga's right-hand man, who succeeded Nobunaga in uniting all of Japan, was a man named Toyotomi Hideyoshi, who Nobunaga nicknamed Monkey. Grodd fills Hideyoshi's role in the movie, so they had a [[EverythingIsBetterWithMonkeys literal Monkey]], play Monkey!

** [[Manga/JojosBizarreAdventurePhantomBlood A monkey cannot stand against a Human?]] Well, Dio, since [[Creator/TakehitoKoyasu you're]] the monkey now, you might want to revise your words...

** Damian using a magic flute to summon armored monkeys? Alright. The monkeys standing on each other shoulders to form a giant robot monkey? This is getting silly. Bats join forces with the monkey to form a giant Batman? Check please!

* OlderThanTheyThink: Generally, it's pretty rare for Joker and some of the other mentally insane Arkham rogues to learn Eastern martial arts that enable them to somewhat even the odds with Batman in a fight. However, an even earlier instance of this than ''Batman: Ninja'' occurred in ''WesternAnimation/TheBatman'' where The Joker and The Penguin were AdaptationalBadass characters who were extremely proficient martial artists, with Penguin being explicitly established as having gained his fighting skills from the Far East.

* SpiritualAdaptation: The campy and over the top setting that heavily relies on RuleOfCool, combined with the movies glitzy color palette bring to mind ''WesternAnimation/BatmanTheBraveAndTheBold''. It also helps that the movie has elements in it that wouldn't be out of place in an episode of the cancelled cartoon, such as the members of the Caped Crusader's Rogues Gallery piloting thematically appropriate mechas designed for them, which later on combine into a gigantic mecha with Joker's face, to which Batman responds with a giant made out of monkeys, which then gains the help out bats to become a gigantic version of Batman himself.

** The idea of the Joker [[spoiler: hypnotizing himself sane so that he could fool Batman]] could make a pretty interesting story-line all in itself, but it's only a minor plot point here.

** On the other hand, what may be a by-product of this is that at least in Netflix, the English subtitles don't match the English audio track half the time; For example, Joker's early line "I have to say I've really enjoyed the sushi here" has the subtitle "I thought you'll be here, too. So I was looking for you." It's usually the same but it's a bit irritating if you use both the English audio and subtitle track.

* CantUnHearIt: Anime fans might recognize Joker's Japanese voice actor, Creator/WataruTakagi, as the same actor who played Okuyasu Nijimura in ''Manga/JojosBizarreAdventureDiamondIsUnbreakable''. 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''.

** None of the villains besides The Joker, Harley, and Grodd get that many lines and are pretty much interchangeable.

* TheyWastedAPerfectlyGoodPlot:except

** In ''WesternAnimation/BatmanBeyondReturnOfTheJoker'', Terry the new Batman states, "I was never a Robin". Terry's voice actor, Will Friedle, voices Tim Drake, the third Robin in this movie.

** Catwoman teases Grodd about eating a banana, calling it 'rather cliche.' Grodd's response?
--> '''Grodd''': Says the catburglar in the cat costume.

* HilariousInHindsight: ing

* WhatDoYouMeanItWasntMadeOnDrugs: This movie takes place in feudal Japan, and involves Joker as a daimyo with combat skills equal to Batman's, Bane as a sumo wrestler, a re-purposed Arkham Asylum converted into one of several mobile mechanized castles that all combine into a gigantic battle robot, a magic flute that can command millions of monkeys to work together like a colony of ants to build a large humanoid gestalt form, a nearly endless swarm of bats that combine with the aforementioned monkeys to build an even larger (and indestructible, or at least flame-proof) giant Batman...[[ArsonMurderAndJaywalking and a cheerful and playful Damian Wayne who loves his pet monkey]]. If the producers weren't on drugs, maybe they ''should'' have been, so the end result might have come out a little more sane!

** Many fans felt that it was bizarre to include all of Bruce's children excepg for Cassandra Cain, who actually has Asian ancestry (albeit Chinese as opposed to Japanese).

* FoeYay: The Joker makes various HoYay comments about how exciting fighting Batman is, and Harley does some LecherousLicking to Catwoman, who lampshades their fight as [[GirlOnGirlIsHot "girl on girl" action]].

* {{Narm}}:TengenToppa
"* For some viewers, Damian's hair. While many understand that it is in fact a historically accurate hairstyle there are quite a few people who've admitted that they find it too silly to take seriously due to modern standards.

** Damian using a magic flute to summon armored monkeys? Alright. The monkeys standing on each other shoulders to form a giant robot monkey? This is getting silly. Bats join forces with the monkey to form a giant batman? Check please!

* SugarWiki/FunnyMoments: Catwoman teases Grodd about eating a banana, calling it 'rather cliche.' Grodd's response is brilliant.
--> '''Grodd''': Says the cat burglar in the cat costume.
** The fact that after Joker commandeers Grodd's fortress and thus the resulting Combined Mecha, he abruptly drapes a balloon tarp with his face over the command deck to give the robot his own personal touch.

* 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 (''with'' HumongousMecha and a climax built entirely around them) and the title character's 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/JoJosBizarreAdventure'', the screenwriter for ''Anime/GurrenLagann'' and ''Anime/KillLaKill'', and character design and English-language screenwriting from the creator (and producers) of the ''Anime/AfroSamurai'' manga, series, and film. More than a few fans were drawn in simply by being fans of the creators' other work.

** Some people have admitted that the story's setting leaning so heavily on SchizoTech might perhaps be ''too'' much of a good thing, and the time travel plotline as unnecessary, preferring a more straightforward, slightly more realistic Elseworlds period piece like ''[[WesternAnimation/BatmanGothamByGaslight Gotham by Gaslight.]]'' "Batman in a JidaiGeki samurai story" and "Batman in a ridiculous, over-the-top HumongousMecha anime story" are both great ideas, but 80 minutes isn't quite enough to properly do ''both'' of them justice.

** Gorilla Grodd originated as the ArchEnemy to ComicBook/TheFlash, and though he's treated as a general DCU villain these days, he's not exactly the first that comes to mind when someone thinks "Batman villain".

* WhatDoYouMeanItWasntMadeOnDrugs: This movie takes place in feudal Japan, and involves Joker as a daimyo with combat skills equal to Batman's, Bane as a sumo wrestler, a re-purposed Arkham Asylum converted into one of several mobile mechanized castles that all combine into a gigantic battle robot, a magic flute that can command millions of monkeys to work together like a colony of ants to build a large humanoid gestalt form, a nearly endless swarm of bats that combine with the aforementioned monkeys to build an even larger (and indestructible, or at least flame-proof) giant Batman . . . [[ArsonMurderAndJaywalking and a cheerful and playful Damian Wayne who loves his pet monkey.]] If the producers weren't on drugs, maybe they ''should'' have been, so the end result might have come out a little more sane!
* {{Woolseyism}}: An unintentional example. Due to time constraints, the dub team had to work entirely from [[https://www.gamespot.com/articles/why-batman-ninja-in-english-is-so-different-from-t/1100-6458513/ a heavily summarized and poorly translated version of the script]], meaning a lot of the dub was essentially brand new dialogue, written entirely based on the animation. Most fans agree that they did a pretty good job though.

* SoBadItsGood: This isn't bad movie, if you aren't taking it seriously.

* SpiritualSuccessor: The campy and over the top setting that heavily relies on RuleOfCool, combined with the movies glitzy color palette bring to mind ''WesternAnimation/BatmanTheBraveAndTheBold''. It also helps that the movie has elements in it that wouldn't be out of place in an episode of the cancelled cartoon, such as the members of the Caped Crusader's Rogues Gallery piloting thematically appropriate mechas designed for them, which later on combine into a gigantic mecha with Joker's face, to which Batman responds with a giant made out of monkeys, which then gains the help out bats to become a gigantic version of Batman himself.

* FanficFuel: Or perhaps "Fanart Fuel" (as well?). Just imagine what Mr. Freeze or The Riddler would've looked like in Feudal Japan.

** Many fans felt that it was bizarre to include all of Bruce's children save for Cassandra Cain, who actually has Japanese ancestry.

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

** {{Macekre}}: 90% of the plot being rewritten for the English version based solely on the animation alone didn't get the English version of the movie much love from anime fans expecting modern localization standards. It doesn't help that the official subtitles don't match with the Japanese version either, leading to a fansubbed version.

** In ''WesternAnimation/BatmanBeyondReturnOfTheJoker'', Terry the new Batman states, "I was never a Robin". Terry's voice actor, Will Friedle, voices Tim Drake the third Robin in this movie.

** Bane as a sumo wrestler. He looks ridiculous, but it's so over the top its likable.

* SugarWiki/VisualEffectsOfAwesome: ''Batman Ninja'' is already shaping up to be a very good looking movie, especially with the SceneryPorn.

* {{Woolseyism}}: An unintentional example. Due to time constraints, the dub team had to work entirely from a heavily summarized and poorly translated version of the script, meaning a lot of the dub was essentially brand new dialogue, written entirely based on the animation. Most fans agree that they did a pretty good job though.

* {{Earworm}}: The Japanese Rap that plays when in the climax when the giant robots combine under Joker's control is very, very catchy.

** Damien using a magic flute to summon armored monkeys? Alright. The monkeys standing on each other shoulders to form a giant robot monkey? This is getting silly. Bats join forces with the monkey to form a giant batman? Check please!
