If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

The film makes a home in your brain and the only cure is to see it again.

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."

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.
