I just sat down to watch this, with family.
What we expected: a typical Hollywood action-packed blockbuster with a great idea, destroyed in all ways possible.
What we got: an interesting somewhat plausible - still a little predictable - script, decent actors (no Oscar nominations here), great action, and a clever twist.
Fun entertainment, but if you pay attention to the details from the start, you'll have the ending figured all out.
