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.

The film's masterful storytelling did its job. The message was clear. No need to overdo.

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

While it doesn't offer any answers, it both thrills and makes you think.
