The story seemed interesting, and I expected a much better film; it just kept getting worse as the film continued.
Bullock's character was just too unbelievable; the only possibly credible characters would be the two high school students.
Editing and lighting were not as good as they could have been; directing was lousy. And indeed this film is not as thrilling as believed: it is really stupid.
A total disappointment. Hollywood needs a reality check.
