One of my all time favorites.

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

After playing with our expectations, this turns out to be a very different sort of film.

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.
