A Masterpiece!

It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

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