Admirable film.

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.

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.

The best films of this genre always show a path and provide a takeaway for being a better person.
