The acting in this movie is really good.

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
