So when it was a nobody who wrote it, it was crap but now that it is by Rowling it’s golden? Me thinks it is still crap, it is just that now it’s Rowling’s crap.
Actually, I read some reviews that were written before she announced she was the real Author and the vast majority of them were favorable. Also, many of them(the reviewers) speculated that it was written by an experienced author, not a newbie. I think the reason it wasn't selling was because it was by a new author, not because it wasn't any good.
