Well, I have some positive and some negative comments. Positive: The movie has a good cast, great direction/editing and music. Its great and very well made.
However, I disagree with the message its trying to send across. The plot sympathizes with the terrorists and shows USA in a bad light. After suffering 9/11, USA did whatever it thought was to the best of interest for the nation. Some people may not agree to it, however, still it does not justify terrorism.
India has also suffered several terrorists attacks in the recent past. India as such, has not done much to fight terrorism and I dont think that such humane approach to terrorism is the need of the hour. India or USA got to do whatever they got to do to fight terrorism. An Indian movie sending a terrorist friendly message just does not gel with me. Terrorism can never be justified.
