How sad is this?

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.

Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
