I've read every Jane Austen novel except Northanger Abby, though I read most of them when I was in my mid-20s. Probably about the time Clueless came out. Not too long ago I read Mansfield Park for the first time, and I really really didn't enjoy it. I know it mostly isn't a fan favorite, but I really didn't like it at all. More than that it made me wonder if I'd like her other works if I re-read them again. Basically, I hated every single character (well, Fanny was ok) and just wanted someone to punch them all in their faces to shut them up.
I suppose I'll have to re-read one I liked and find out.
