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 movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

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