No seriously, I love Jane Austen for more than Mr. Darcy, although he is a big part of why I adore her books.
I like her books because they are funny and romantic and they contain fascinating side characters and insightful commentary on human nature.
My favorite novel of all time is Pride and Prejudice. In this story both hero and heroine are flawed. Elizabeth is clever, but she is quick to judge. Darcy is intelligent, but arrogant. Some might dismiss this story as a Cinderella story because Elizabeth ends up with Darcy, who is rich, but in this story the Prince (Darcy) actually changes and becomes a better person by the end.
When Elizabeth refuses his first offer of marriage (very unCinderella-like), he is humbled. But then he writes a letter that makes her realize that she has been judging him harshly. So they both change for the better, then they deal with foolish/obnoxious family members (Darcy rescues Lydia and Elizabeth stands up to his aunt Lady Catherine) which shows the reader that they deserve happiness. And finally, they speak up, taking an emotional risk to declare their feelings and they are rewarded with a great, lasting love.
