Okay, usually they're longer than a movie you'd see in the theater, but they're so worth it. The recent Masterpiece Theater version of Jane Eyre just reminded me of how awesome the book is.
Also, Jane Eyre is pretty much the perfect book for a nerdy 14 year-old. It's way angsty--no one understands Jane! except Mr. Rochester!--and Jane isn't one of the pretty, bouncy girls. And it's really dark and creepy. Plus, you love it even more when you return to it years later.
Rock on, Bronte.
