This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

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 those movie experiences that is so good it makes you realize you've been grading everything else on a curve.

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