Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
