Very well executed

Very very predictable, including the post credit scene !!!

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."

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.
