I’m preparing to really criticize _Batman Ninja_, but first, a note: several times while watching it, I questioned whether it might be enjoyable if experienced with others. I watched it alone, on a day when I wasn't feeling well and was stuck in bed, and that’s the perspective I’m sharing here. Films don’t need to be realistic or conventional to be good. They don't even have to make sense. Sometimes a movie can just be silly entertainment, and other considerations become unimportant. However, generally speaking, the better a film is—that is, the more you as the viewer are enjoying yourself—the more oddities you’re willing to overlook. It’s easier to accept an extraordinary suspension of disbelief if most aspects of the movie are solid. If there are issues, but you only have to tolerate a small amount of absurdity, it'll likely be fine. But occasionally, a film has absolutely nothing going for it and still demands a massive leap of faith from its audience. _Batman Ninja_ falls into **that** category. I could probably focus on any single element I disliked about _Batman Ninja_ and write an entire review around that one problem. Since I usually prefer to keep these reviews brief, instead of discussing the plot, how it differs from the original material, the character decisions, the voice acting, the animation style, the sexism, the science, the logical errors, the design choices, the dialogue, the absurdity, the internal contradictions within its own world, the fact that I actually fell asleep at one point due to boredom, or any number of other issues—many of which I’ve forgotten or would take too long to explain—I'll simply say: It is the worst Batman movie I have ever encountered. _Final rating:★ - Worthless. Steer clear._
