Excellent but underrated film

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 easily one of the freshest, sharpest and most enjoyable films of this year.

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.
