mania.com has an article about
The 7 biggest Mary Sues in Pop Culture.
Of course, Eragon and Bella are on it. My favorite line from the article would be "Congratulations Chris: you’ve officially turned The Hero with a Thousand Faces into every douchebag football captain who ever ruined high school for the rest of us."
Also, I love that the author has Lisbeth Salander on the list. Finally, proof that I'm not alone with my opinion that she's a total Sue (as is the male lead of the books).
