We tried this new adaptation of Emma last weekend and I was very happy with it. It's the first time I've actually liked Emma, except in the book. She's still a bit silly, like she's supposed to be, but she's a lot more than just a silly girl. I thought it was very well done.
So now, of the more recent BBC versions of Austen, I like Emma, Sense and Sensibility, and Pride and Prejudice. Persuasion is, unfortunately, awful. I'd like to see a remake of Mansfield Park; like Emma, at least before this version, Mansfield Park hasn't had a good film made of it yet.
