I think most of all it's popular and successful, but isn't of interest to EVERYONE here.
As much as I feel she kind of stole Terry Pratchett's thunder, by being the new biggest selling author in the UK, and writing fantasy books, she's done well, she's created a world of her own that many many people enjoy, I don't think any of it's 'bad', it's just bleh..child actors put me off immediately, I just want to slap the precocious little buggers.
Of course they're all older now, so I'll even forgive them having been kids once
Pratchett is still the UK's most shoplifted author tho, and he's still miles ahead of Rowling in writing, volume, talent, beards and hats. Also, even tho 'Going Postal' was hacked down to a tiny part of its original tale to fit a movie, the movie of the book was still better than any of the HP ones imo.
My argument for Pratchett over Rowling, is that Rowling's books are about kids who become wizards, Pratchett's books are about our world and our lives, reflected in a warped mirror that is the Discworld, and this leaves him open to infinite avenues of new tales. I just wish for his alzheimer's disease to be very slow and let him create at least a few more books before it takes his magic away. (Selfish in a way, but damn, the end of the Discworld will be a sad day.)
In the end, HP, Twilight, whatever, if it gets kids reading they're far more likely to read other stuff and widen their interests and knowledge, and that's worth making Meyer a millionaire a few times over and I don't begrude her or Dan Brown or Rowling (who I don't put in with Meyer or Brown, while I don't like her stuff I know it's creative and well written) becoming rich and famous, all the time Paris Hilton is rich and famous for just owning hotels and a vagina.
After all, if kids listen to Busted and McFly and the like, and as a result take an interest in other guitar music, surely that's worth letting the bands live?
