Batman Ninja (2018)

Batman Ninja arrives as a 2018 curio, a Japanese-American co-production that yanks the Dark Knight out of Gotham and deposits him in feudal Japan, where the Joker has installed himself as a warlord and the castles turn into giant robots. Takashi Okazaki, the creator of Afro Samurai, handled character design, and the animation from Kamikaze Douga and YamatoWorks carries a woodblock-meets-mecha sensibility that is genuinely striking. The plot is a delivery mechanism for spectacle: time displacement, warring daimyo, a monkey the size of a mountain. Nothing more is claimed, and nothing more is needed.

Judged against contemporary social consciousness, the film is close to a null set, and it seems content there. The entirely Japanese voice cast reflects the ordinary staffing of a domestic anime production, not a diversity initiative, so the casting ledger stays modest. There is no LGBTQ content, no racial commentary, no environmental appeal, no indictment of wealth. Catwoman, Harley Quinn, and Poison Ivy handle themselves in combat and move chunks of the story, yet the film advances no feminist argument and never troubles the gendered conventions of the genre. The feudal setting is scenery. Time travel here is a premise for sword fights, not a revisionist reading of history.

Most crucially, the film refuses to lecture. There are no moralizing monologues, no third-act speeches about the way we live now, no lessons tucked inside the castle-mecha mayhem. Grodd schemes, Batman broods, and the whole enterprise resolves in a duel and a mid-credits gag about selling robot furniture to an antique dealer. It is a film with no designs on our conscience. We can respect that, even as we note the classification is straightforward: a spectacular, empty, and oddly satisfying exercise in ninja Batman.
