It's no definitive masterpiece but it's damn close.

The film makes a home in your brain and the only cure is to see it again.

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.

It really made me laugh, but for some moments I was tearing up because I could relate so much.
