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.

The acting is good, and the firecracker script has some excellent ideas.

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.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
