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."

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies

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