I gave this film a 9 out of 10, because it was exactly what I expected it to be.

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 movie is wonderful and true, an act of love in all its contradictions and complexity

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.
