I would only agree with two of the four adjectives used. Moving? sure. Marvelous? I can see how. These two I agree with. Sexy? Well, just Tabu, so that could have been more specific. But I did not find the movie to be funny at all. I even thought some of the depictions of the evolution of Indian culture in America were unfair, and maybe that had a lot to do with the lack of comedic appeal for me. But this is not a complaint I would make to film-makers (although I am not really a big fan of Mira Nair), for they are going by a book (The Namesake by Jhampa Lahiri).
Suffice it to say that The Namesake was one of the good films made last year that could have used a little more oomph, but might not have been able to so without compromising the text that backed it. Tabu and Irrfan Khan make this one tick with excellent performances!
