It's an amazing and heartbreaking story.

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.

Exactly the movie you think it is, but not the movie you want it to be.

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