To me, this movie is perfection.
Matrixiole
Simple and well acted, it has tension enough to knot the stomach.

It's entirely possible that sending the audience out feeling lousy was intentional

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.
