What classic has most surprised you so far and why?

The classic that has probably surprised me the most is a tie between Sense and Sensibility and Mansfield Park by Jane Austen.  I love Persuasion, Emma, and Pride and Prejudice....but I barely finished Sense and Sensibility and I haven't been able to finish Mansfield Park.....I don't know why but it surely is surprising to me that I haven't enjoyed these two Jane Austen classics. Maybe one of these days I will try to get through Mansfield Park and I will try Sense and Sensibility.
