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."

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
