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."

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.
