I am sorry, I seriously don't understand why this book is so famous. I mean, yeah, it was good, ('okay' maybe) but it's not worth the popularity it has received.
Its not something you'll dwell on for days and if I am being too honest I was eager to be done with this book. I skimmed through most of the pages and glad that I finally reached the end.
Still, some people who are into this genre might like it better, but not me. But I'd like to congratulate Aravind Adiga for winning a Booker for his effort.
