It's funny watching the elements come together in this complicated scam. On one hand, the set-up isn't quite as complex as it seems, but there's an easy sense of fun in every exchange.

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."

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
