Last Word:The first half of the film is very good. The second half drags a bit because there is not much of story remains once the identity of killers is revealed. Director handled the romance in the film in a matured way. There is no problem of Tamil nativity in this film because the subject is typical Hollywood cop thriller type. The major plus points of the film are director's taking and Kamal Hassan. On the flipside, the serial killing concept of the film might become too serious for a general entertainment seeker. On a whole, Raghavan is a decent film which you can watch at leisure. Box office wise, the film has potential to do well in A centers.
