It's like The Room, except it's done on purpose, and an edgy ninja show. That's it. There is no comedic timing, or witty lines to indicate when you're expected to laugh. Under Ninja just throws the most absurd concepts and cliches at you, while remaining dead serious for the entire runtime. And the worst part is that all of it starts to make sense the longer you watch. I saw another review call it "an anime watcher's anime" and that might be the best way to describe it. Someone without extensive background knowledge would have a difficult time seeing the irony in this show.
