Lack of good storyline.

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
