Oddly, I can't bring myself to hate Stephanie Meyers (author of Twilight) simply because it was something new. Yes, the book was written pretty appallingly, the pacing was arse, the characters were all part of some sort of sexual fantasy of her's and almost universally dislikeable, but she did something new. She tried to simulate a typical romance story with aspects of horror and the occult, and whilst it's not going to go down in history it's the rabid fan-base I hate more than the author. I can avoid book and films easily, people are harder to do so. The book is pretty much known as trash-teen-goth-crap, so it doesn't offend me. If it was hailed as the messiah of all literature I'd have harpooned the author. Also, from the way the author penned the character of 'Bella', we all know she's a nymphomaniac *****, so she's entirely dislikeable, but not quite hate-able for me.
Similar to Paolini, the guy was seventeen when he wrote his book. I thought it was pretty damn fantastic for a guy his age for a first book. Again, won't go down in history but I enjoyed the first two books. Admittedly Brisingr has now set the series in a bad direction, but for the most part I'd like to think if I was his age and was writing my first novel it'd be as good as his. I don't get a sense of pretentiousness from the books, as if they're wallowing in their own successes. The guy wanted to write a story, and now he's getting money for it because it founds it's niche. Kudos to him.
Now, the Bronte's. There's a family of people to despise.
EDIT- Also, I think J.K. Rowling totally earned her success. She didn't make the best books in the world, but they're highly accessible to pretty much all ages, languages, and both genders; that's got to count for something.
