Disappointment for a huge fan!

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

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