What famous book did you not like, or not understand?

I was perplexed by how anyone could even enjoy it nevermind say it's the greatest book ever written. And it's not like I don't like the clics, I love To Kill a Mockingbird and The Catcher in the Rye, and I am currently reading War and Peace and thus far I think it is brilliant. But the Gatsby seemed pointless to me and I would consider probably one of the worst books I have ever read.
