Miley Wants to Leave Hannah Montana — Good Idea or Bad Idea?

Miley Cyrus hit a bookstore in LA yesterday, as she gets back into her California routine following a trip to Australia with her The Last Song costar and now boyfriend Liam Hemsworth. She took a break from Hannah Montana in order to work on the movie, and while she's currently working on the fourth season of the show, Miley apparently wants to make it her last. Miley has expressed interest in pursuing other music and film opportunities, and over the past few years she's certainly had some trouble maintaining a kid-friendly image. So, tell us — do you think it's a bad idea or a good idea for Miley to leave Hannah Montana?
