At 15, did not enjoy it at all. At 36, thought it was a masterpiece. But that goes for so many books. Anna Karenina at 12? Was underwhelmed. At 30? Was both enchanted and devastated. When I read Tess of the D’Urbervilles as a kid, I found it dull and it made so little impact on me that I barely remembered anything apart from it being depressing, having a sad ending, and a rough outline of the plot. I read it again when I was like 26 and it utterly destroyed me, to the point where I thought of it constantly for like a month.
