Good movie, but best of all time? Hardly . . .

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."

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.
