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

It is so daring, it is so ambitious, it is so thrilling and weird and pointed and powerful. I never knew where it was going.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

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