Excellent, Without a doubt!!

It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

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."
