I find a lot of Jane Austen's work translates better on film. I love "Pride and Prejudice" and the A&E version is stellar. "Persuasion" was more difficult to read, but a FABULOUS movie (With Amanda Root).
"Emma" is a one of my favorite books, but I can see how it would be tough to slog through. I have a Jane Austen mood. Then, I'll sit down and read all of the ones I own in a week or two. For me, the language, the style, everything is a mood.
