I'm really impressed. This Technological thriller was stunning. This genre isn't very popular but should be. Gerard Butler made this film - phenomenal acting. He should leave useless comedies and focus on more serious roles like this one. Of course the storyline wasn't that original. We could see many similarities with other technological thrillers like The Net, Disclosure, The Specialist, The Assassination File, Untraceable and even Minority Report but still it was superb movie!!!
