The "Could and Should" have been classic.
Kolaveri could have been providential. Dhanush, the clever and thinking pro that he is, acutely aware of his limitations, times and chooses a script that will help him get accepted in main stream National cinema. A dream Debut.
Happy for Sonam, she been for quite a while, as much as Ranbir, probably lands up a role, that should get her recognition and better roles. While she breezes through the role with a bewildering array of emotions, she is best when her innocence gets exacerbated by her beautiful smile.
The third star of the movie of course is A.R. Rahman, who keeps you intoxicated with a high octane numbers and background score.
The first half is sheer movie making magic and the second half makes this movie as a "COuld and Should" have been classic. From nowhere the thinking caps seem to have disappeared until the climax which has been beautifully adapted from American Beauty.
Last not but not the least for the cinematographers and the dialogue writer for capturing the flavour of Benaras/Varanasi!!!!!
May be you could just walk out after the interval and feel exhilarated.
