A brilliant film that helped define a genre

In truth, there is barely enough story here to make a film.

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.
