If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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

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.

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.
