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.

One of the best movies of the year! Incredible from the beginning to the end.

Yes, absolutely, there is fun to be had, as well as many, many things to go boom, all amid an atmospheric urban jungle.
