The movie was much better than I had expected. It started out rather poorly, but quickly gained speed and showcased some of the best acting I've seen in a while. My only complaint is the change in the story surrounding the first gun fire and in particular, the negative way in which the custodial worker was depicted - slothful and rather ignorant. Why not stick to the way it really happened?? The scenes from the camera showed a well-dressed, professional cafeteria manager who was actually the person who was the target of the first gun fire. Why was this depiction of the custodian necessary? On the job, but sitting in the car with headphones listening to music, and later, dancing towards the school still wearing headphones. Not realistic at all!!
