So, what do you consider good writing?? And please don't give such blase answers like Crime and Punishment.
Agreed what you say about the celebs and also that The Da Vinci Code is never going to win the Booker, but it has everything a thriller needs and that is what it is supposed to be. And in my honest opinion, a book that keeps a reader engrossed is far better than that which only the critics admire.
Hence I suggest that you keep your opinions about bad writings to yourself and let the readers decide what is good and what not.
