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."

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.

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

The acting is good, and the firecracker script has some excellent ideas.
