This book is about everything in Mumbai from slums, dance bars, movie stars, gangsters, locals, riots, muslims in Mumbai, Balasaheb Thakray, Mumbai police...
Suketu has written too lengthy descriptions of people and events. His thoughts do not seem to be cohesive.
He has made too many derogatory remarks on Maharashtrians and Marathi Language, that coming from a Gujju is ridiculous. He himself does not speak a great language like Sanskrit either.
This book is full of complaints about Mumbai.75% things mentioned in the book are not 'Mumbaiyaa'. There are stories about Vidhu Vinod Chopra (film director) which are refuted by Vidhu himself so this takes away the credibility of the other stories mentioned in the book.
Suketu, if you are aware of so many problems about Mumbai and you have so many contacts (as you have mentioned it repeatedly in the book) then why don't you come up with solutions and start acting on it?
Out of 500 pages in the book 50 pages have really some substance.
What is really good about the book:
Suketu's immense research, he has interviewed people from slums, movie stars, gangsters, politicians to bar dancers.
The book is worth a read for those 50 pages.
