In 2008, about a week before The Dark Knight hit theaters, Warner Home Video and DC Comics released Batman: Gotham Knight, an excellent collection of six anime shorts from the studios behind Ghost In The Shell [Production I.G.], Paprika [Madhouse], Steamboy [Studio 4°C], and Noir [Bee Train]. Now, ten years later, we have its spiritual successor in Batman Ninja (Blu-ray/DVD/Digital combo pack, DVD, digital; with digital 4K to come), a full-length anime movie that ranks alongside Batman: Gotham Knight as one of the most unique, intriguing, and exciting Batman animated movies.
