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.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

This movie tries so hard to be funny, yet it falls flat every time. Just another example of recycled ideas repackaged with women in an attempt to appeal to a certain audience.

One of the most extraordinary films you will see this year. Take that as you want.
