Stretching back to the 1940s serial shorts, there have been over seven decades of Batman cinema to date, which makes adaptations of the unfathomably long-running comic book series common enough to be considered their own separate movie genre. As such, there are plenty of tropes & verbatim repetitions of scenes in onscreen Batman content that have become punishingly familiar to audiences who regularly seek this stuff out. No Batman movie need ever show a young Bruce Wayne witnessing his parents’ murder in a back alley again, for instance, as it’s an image that’s been deeply chiseled into our minds over the decades (right down to his mother’s broken strand of pearls skittering across the pavement). Many recent Batman movies have reached for a more distinctive novelty in their narratives as a result, especially the animated DC movies. 2018 alone has already seen the release of a film where Batman teams up with Scooby-Doo, one where he battles Jack the Ripper in a steampunk arena, and one where he crosses over into the treacherous, transcendent world of anime. It’s that last example where Batman cinema has likely reached its most absurd novelty to date, even promising in Catwoman’s opening dialogue, “You think you’ve heard every Batman story? I promise you haven’t.” The story Batman Ninja proceeds to tell after that tease is indeed one I’ve never seen before. What’s up for debate is whether it’s, factually speaking, a story at all, as opposed to a chaotic collection of incongruous tangents & flights of fancy. What’s clear, either way, is that it’s admirably bonkers in a way more Batman movies could stand to be, animated or otherwise.
The concept of mashing up Batman with anime sounds like a nerd’s wet dream, a juvenile pleasure impulse Batman Ninja attempts to live up to in every self-indulgent frame. With intense character redesigns from Japanese manga artist Takashi Okazaki and an impressive team of traditionalist animators, the movie is almost well-crated enough to pass itself off as an art piece instead of what it truly is: nonstop over-the-top excess, a shameless sky-high pile of pop culture trash. The film begins with Batman being transported back to feudal Japan with “a time displacement device,” where he must stop anime-redesigned versions of his infamous foes from taking the country over & rewriting history. The Joker, Poison Ivy, Two Face, The Penguin, etc. are introduced like Pokémon selections in a video game. Each present a different setting-appropriate challenge to the Caped Crusader as he anachronistically drives his shape-shifting Batmobile around feudal Japan. The movie chases its own impulsive whims from moment to moment in these barely-connected conflicts as Batman subdues his enemies one by one, struggling most to conquer The Joker, as always. The resulting spectacle is pure lunacy. Batman sumo-wrestles Bane in a mech suit. The Joker’s goons manifest as samurais in welded clown masks. An army of monkeys assembles to form one giant monkey that challenges a similar gigantic Batman gestalt (composed of bats, naturally) to a climactic kaiju battle. I don’t know that I can praise Batman Ninja as disciplined comic book storytelling, but it’s certainly a novelty as visual spectacle, something that must be seen to be believed.
Ostensibly, there’s a long-running connection to ninja training in Batman’s origin story that could potentially be used to justify this absurd indulgence. If nothing else, Christopher Nolan’s Batman Begins could’ve easily been retitled Batman: Ninja School without much of a fuss. The truth is, though, that Batman Ninja seems entirely unconcerned with justifying its own for-their-own-sake impulses. Its experiments in the newly discovered artform of Batmanime seem to be born entirely of “Wouldn’t it be rad if __?” daydreaming. It’s a refreshing approach to Batman storytelling, as most of the character’s feature-length cartoons are much less comfortable with fully exploring the freedom from logic animation affords them. In an era where memorable novelty is essential to keeping Batman narratives viably fresh, it’s difficult to imagine Batman Ninja being outdone on a measure of pure imagination, even if it makes zero goddamn sense.
