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.

After playing with our expectations, this turns out to be a very different sort of film.

The best films of this genre always show a path and provide a takeaway for being a better person.
