I am indifferent to twilight, but I bet if I read/watched it I would feel about it the same way I feel about Harry Potter.
I LOVE Harry Potter. But I cannot stand the books and movies written by JK Rowling. I thought it was a horrendous story full of bad plot-holes, shoddy explanations, annoying characters, and a complete cliche.
But I love the Harry Potter universe. I read fanfiction at least an hour a day. I am very thankful that Rowling wrote her stories, even if I didn't like it, because it allowed other people, who are far superior writers, to entertain me.
I've read some twilight fanfiction. It's pretty good. So i bet I would feel the same way.
