Let's be realistic.

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."

After playing with our expectations, this turns out to be a very different sort of film.

The best films of this genre always show a path and provide a takeaway for being a better person.
