The saga shown in The Namesake is nothing new. It is shown in so many independently produced US Indian Productions including American Desi. Having said that, the movie was touching (remember the movie was made with 1970's in mind) with some brilliant peroformances by Tabu, Irfan & Kal Penn. One has to say, what FF Coppola did to Godfather, Mira Nair has done to The Namesake, where the screenplay actually exceeds the richness of novel.
However, as an Indian youth living overseas, I find storyline so repetitive and wildly emotive. The new generation of Indians migrating today to West, will not feel the same way, as the Indians who did 3 or 4 decades did.
