“Batman Ninja” (**1/2 out of four) was an intermittently entertaining animated feature in which Batman (voiced by Roger Craig Smith) and many of his allies and adversaries are transplanted to feudal Japan where his rivalry with the Joker (voiced by Tony Hale) is reignited. Animation ranges from amateurish to colorful and striking but the story gets too lumpy. Highlight is a final action fight between Batman and Joker involving Japanese samurai.
