Best movie ever!

It is not deep, but it is fun to watch. It does have a bit more of an edge to it than other similar films.

How wonderful it is to see this fine actress carry a film and carry it so beautifully.

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."
