A character you disliked at first but came to like later? Or vice versa?

It's funny when you read Pride and Prejudice and find yourself feeling the same way the narrator does: Disliking Mr. Darcy for being arrogant and standoffish in the beginning, and then gradually coming to like him as you learn more about him indirectly through others but also eventually directly.

But I've also had experiences where I did not feel the way the narrator or author appeared to feel toward a character. And sometimes these feelings changed over the course of the book.

I may be the only one who feels this way about the much hated Javert, for instance, from Les Miserables. I wouldn't say I came to like him but by the end but by then (and I won't say what happens) I saw his internal torture and outward sign of that suffering, which to me finally made him human.

Have your feelings about a character changed dramatically as you read a novel?
