Odelecol Pretty good movie overall. First half was nothing special but it got better as it went along.

SanEat 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."

Lidia Draper Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.

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