It's a movie that knows the games very well and hopes you do too.
I don't really mind if a movie has no story as long as the moment to moment stuff is good. In this movie, the music and action choreography are great, but I feel like it lacks a certain something to make it "Super". While I wouldn't call the humour terrible, it's also not more than the odd smirk. Bowser's development in this movie is so messily done too.
