Yeah yeah, I saw it too. In the interests of scoring brownie points and all that.
The movie is not great but it is better than the book. Other than the exocticisation of Calcutta and the Indus Bank billboard with the A Ganguli trunk fiasco, there are no glaring put offs. But is it good enough for one to take the pain the go to the theater and watch it? Yes, for one reason. Irfan Khan. The man carries the movie from the first frame to the last; even when he is not physically there, he seems to fill the frame. It does not matter what the other characters do or do not do. The only similar performance I can think of from a recent Indian movie is Seema Biswas in Water.
PS: Kal Penn is not bad. Really. Its not like he has a meaty role and didn't perform or anything. Its hardly his fault if he is expected to do ntohing.
PPS: BM, I see your point about the camerawork not being very flattering to the Indian women characters. The 2 inch makeup on all their faces is a little strange but to me, it wasn't too jarring. Probably because everytime I have been in any sort of a Bong gathering, the 2-inch makeup has always been very visible to me :)
