When Masterpiece Theater aired a new film version of Emma this last January it made me want to read the book again after watching it. Unfortunately, my Austen books were in storage (it was sooo depressing to have all my books in storage!). Now of course, my books are all out and after buying my Emma DVD (I love the new movie; definitely recommend it to all Austen fans) I was finally able to read it. Emma is not my favorite Austen book, but that's not too much of an insult because I love all of Austen's novels. I think there's something about an Austen film adaptation that completes the enjoyment for me, though. Jane Austen is notorious for her sparse romantic details (proposals summed up in short third-person sentences, important conversations/looks etc... glossed over, NO kissing or other physical contact described), and so I love watching the movies because they fill in those gaps.
I think one of the reason Austen's novels are so popular is because so much is left to the imagination. The plots are fabulous, but the details are sparse, leaving readers to create their own perfect love story in their minds. I am an Austen enthusiast, though, so maybe I'm a bit biased, but I think she's a genius.
