Warning: The movie contains violent scenes and abusive language which might not be suitable for all audiences. This is NOT a movie to go wid ur family or girlfriend!
The movie is a typical Crime scene investigation story directed by Apoorva Lakhia, based on the real shoot-out by Mumbai PI Khan on 16th Nov, 91 .
Movie starts with Sweet sweet Diya Mirza(Who is a reporter in the movie) who is showing the post-shootout scenes at LokhandWala. Stains of Blood on floor and hundreds of empty Bullet-shells on floor are enogh to strike a sensation of panic in viewer's mind.
Right after that, Big B is shown, who is lawyer for the PIs(Sanjay dutt, Sunil shetty and Arbaaz Khan), asking them what exactly happened and why they have to carry out the encounter. In reply to which, the Police wallahs narate the story of how they got the idea of ATS(Anti-terrorist squad) and how it is very efficient etc etc.
Character of Maya Dolas is extremely well-performed by Vivek. This man actually sucks in romentic roles but does exceptionally well when shown as an arrogant, care-less guy. (Company, kaal and now, Shootout!) His performance is awesome... The 'Bhai' wallah attitude is ultimate.
Rest of the Gundahs also do well. Tushar is doin a nice job here working as a top shooter of the gang.
Sanjay Dutt, Suneil Shetty and Arbaaz also do very well in the movie.
The only drawback of the movie are the two bar dances which are put without any meaning. Also, I expected to see Maya rising high and then falling. Here, Maya is shot down before he can actually rise. (Okay, as this is based on True Rumours, this one is forgiven!

)
In all, a one time watch. But as i said, dont go if u dont like violence.
