Okay, finally saw it.
In short, this was a movie that didn't know what it wanted to be. Was it a martial arts comedy, a sort of
Beverly Hills Ninja with animals? Was it a stirring action adventure? The hero's journey of a callow youth? Even the visual style was confused. It tried to be everything, without ever clearly being one thing, and came out a muddled mess.
Those martial arts sequences, though. omg.
