Nice effects though.

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.
