This movie was a great ride, plenty of action, good leads from Shia LaBeof and Michelle Monahan. I always enjoy Billy Bob Thornton but thought he should have been given more in this role, I loved his interviewing technique with the security guards. Some of the imagery reminded me of other movies, the pylon scene was so like Seven and of course decommissioning Hal from 2001. The computer was entertainingly 'over the top' and would have looked more at home in a Star Wars film. Here reluctantly is the spoiler, the idea of the computer enforcing the Constitution is the type of realm that has always intrigued me. I felt the film could have explored this a little further, without damaging the blockbuster effect. The computer was a type of Jarret from Les Miserables, existing to enforce an ideal but lacking human sensitivity. As governments implement anti terrorist regulations to combat inhuman terrorists, will everyone else's humanity get buried in the sheer energy of human effort? We can't blame a computer, because we program them. This film did nudge me to that train of thought, but as I said it's always intrigued me. Thanks to D J Caruso for the wild ride.
