It is a performances centric movie

When a movie has you begging for it to end not even half way through it's pure crap. We've all seen this movie and this characters millions of times, nothing new in it. Don't waste your time.

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.
