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."

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

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

The movie really just wants to entertain people.
