Very very predictable, including the post credit scene !!!

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

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 a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.
