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.

Exactly the movie you think it is, but not the movie you want it to be.

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.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
