I was lucky enough to have it as part of my college literature course. I had a choice of Greek classics or SciFi and, though I'm missing a TON of Greek classic context these days I do not regret reading ANY of the scifi books! IMO it's a pity I couldn't take both!
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.
