Although it has its amusing moments, in eneral the plot does not convince.

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 movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.
