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

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.

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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."
