Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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

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.

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