Piggybacking on brad and SF's earlier comments about War and Peace....
Most "classic" works I've ever read (or was required to read) sucked. I love reading, love many, many books and authors. But a bunch of supposedly great works bored me to tears. Great Expectations, Great Gatsby, Catcher in the Rye, Lord of the Flies, Grapes of Wrath, all come to mind. Maybe I was too young to appreciate them....I dunno. I didn't enjoy them in the least.
There are books by Jane Austen which are considered classics, and Little Women, none of which I've read, nor do I suspect I'd enjoy any more than any of the others listed.
I see Dostoevsky's are listed as classics, those were fine. I liked The Count of Monte Cristo. Most of that stuff tho, just makes me think it's for pompous people who want to get together at aristocratic parties, sip tea with their pinky fingers out, jerk each other off about the fancy schools they attended and pretend to be cultured and deep and thoughtful and better than the plebes. Give me Harry Potter any day over that stuff.
