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."

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

While it doesn't offer any answers, it both thrills and makes you think.

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
