I wanted to but couldn't!

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."

In truth, any opportunity to see the film on the big screen is welcome.

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