Terrible acting, screenplay and direction.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

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

The film never slows down or bores, plunging from one harrowing sequence to the next.
