If you read it after 25 it's laughably on-the-nose.
In highschool it was the greatest book I ever read.
Some books require the reader to be in a particular place in their lives.
There's a lot of content in the book that reads differently years later. It's extremely easy to criticize outside of the situations present in the book.
Fiction is a good a place to consider alternate worlds, situations outside of the norm, and people with circumstances you'll never (or hope to never) encounter yourself. That makes it a great place to refine morals and reach a deeper understanding of why things might be good or bad.
I find it's easier to get in a time period with visuals compared to a book, but it is a forgivable thing for later generations to 'not get' either way. I certainly don't know all the musicians who influenced the musicians that influenced me.
