The story has been written keeping in mind that a movie will be made out of it in near future. Yep, totally a Bollywood script.
The language of the book is simple, and far from elegant. Too coarse. No wonder a lot of casual Indians like him.
A few lines did make me laugh, and many others showed Chetan Bhagat's desperate attempt to make the book's language funny and elegant. He has miserably at that front.

PS: I might never have read the book if it weren't for a friend of mine whose one comment instigated e to buy it.
