I thought this was a well-execute film with some interesting plot twists and an intricately planned terrorist attack. Yes, I'm sure some overly-analytical movie buff will point out some plot holes bla bla bla. The film is entertaining and the story is presented to you in an interesting way from multiple angles, people's perspectives and all shown starting at the same time frame, around midday on the day of question. The film is well-paced and still manages to tell you enough about the main character but maybe not enough about the protagonists, but enough to understand their motives, and the film has more than enough action to keep you entertained. I definitely recommend.
