It's a mild crowd pleaser for people who are exhausted by blockbusters.

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."

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.
