The music and the animation are amazing!!
BUT the story is badly written.
What I greatly dislike is, in my own words, that the math does not clearly work out or does not at all. Reasons for doing things, consequenses for doing them.
Just for example if you have to travel from one far city to another but get there in a few minutes. Or throwing someone off a roof... would not everyone know there was a murder? Plus doing so infront of a theatre.
It is an animation, so its ok if pigs fly, but up to a measure its ok. Things do not make common sense in the movie
