I wanted to like it more than I actually did... But much of the humor totally escaped me and I walked out only mildly impressed.

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.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.
