A walking paradox

I think the reason why books and films that try to make a Lizzie Bennet-esque character fall short is because they think Lizzie is a "not like the other girls" kind of girl, but really Mary Bennet is like that (one might also argue that Darcy is not like the other girls). Lizzie doesn't hide in a corner with a book during dances. She's friendly, and social, and truly enjoys being around others. She's neither flighty and obsessed with social events or overly sober and reclusive. Lizzie embodies such a healthy balance compared to the absurdities of the people around her that it was easy for her to miss her own pride. Other works that try to have a protagonist with a Lizzie Bennet-esque appeal fail because they leave out Lizzie's general good nature and make their character witty and judgy but also just generally misanthropic and self-absorbed. They try to capture Lizzie's wit but none of her nuance and so end up making a bunch of Mary Bennet characters who the real Lizzie Bennet would have a field day with laughing at their absurdities.
