I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

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.
