Slow pace in the most part of the movie.
It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.
The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful
Watching it is like watching the spectacle of a class clown at their best: you laugh at their jokes, instigate their defiance, and "ooooh" when they get in trouble.
