Gripping story with well-crafted characters

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 sentimental, ridiculously long and only occasionally funny

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