When a movie has you begging for it to end not even half way through it's pure crap. We've all seen this movie and this characters millions of times, nothing new in it. Don't waste your time.

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."

The film never slows down or bores, plunging from one harrowing sequence to the next.

One of the most extraordinary films you will see this year. Take that as you want.
