mira nair is certainly improving/maturing - but the sensitivity which most people associate with the novel/book is somewhat lacking in this movie - but the cast and performances are brilliant! that says a lot about presentday Bollywood, in which only a handful of actors like Irfan Khan and Tabu can do justice to the roles in such movies
Behind the witty lines and the pace of the movie, also lies the untold story of a decaying middleclass value system in bengali society - having suffered the onslaught of a repressive communist dictated govt for several decades, most bengalis have an acute problem of identity, both at the community and social level - and in this mess, there are many kids like the character Moushumi in this movie, who are not sure of their own value systems and make a mess of themselves - having known several bengalis, i can say this for sure
As a footnote - I shudder to think of the spent force AB being cast with the magnetic Johnny Depp in Mira Nair's next movie - perhaps, Mira is doing it with the commercial output in mind, but Naseer or Om Puri wud have been a better and more apt choice - I just hope it doesnt turn out to be embarassing watching big B hamming in front of Johny Depp!
