Although it has its amusing moments, in eneral the plot does not convince.

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."

After playing with our expectations, this turns out to be a very different sort of film.

One of the best movies of the year! Incredible from the beginning to the end.
