Reading through this thread has been very entertaining. I particularly enjoyed Smoothassilk's flounce. A good flounce is hard to find so I was delighted to see one of such superior quality.
Even though the article is an old one I'd like to present my thoughts (for what it's worth).
Full disclosure: I admit to being a rabid pTerry fan. I read anything with his name on and spread the gospel of the Discworld wherever I go.
I think his comments were very reasonable and sensible and I couldn't detect any "laying into".
JKR & HP...I read the first book and got halfway through the second before I gave up. It was like slogging through thick mud. At a certain point I realised that I actually didn't give a damn if Voldemort killed the whole damn lot of them...in fact, I rather wished he would.
However, it's great that she's written a series of books that has captured so many people. I have no opinion of her as a person simply because I couldn't be bothered. As for her writing skills...meh...that's my feeling.
pTerry on the other hand...
His books are not only funny but also thought-provoking. Thadlerian made several insightful comments about the themes explored in pTerry's books.
When I read a Discworld book I often stop to re-read a line or paragraph, amazed at his skill with words. IMO he's made an invaluable contribution to the fantasy genre. There are very good reasons why he is Britain's most-shoplifted author. Even my local bookshop in Cape Town has to keep his books behind the counter.
