Admirable 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.

The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.

The film may be flawed, but its message is not.
