The ideas expressed in Aldous Huxley's Brave New World are indeed both brave and new--some of them still are, no question--but this story is just dry. Huxley wrote lots of essays and other scholarly works. [Yeah, no kidding!] In fact, my copy of Brave New World also includes Brave New World Revisited as well as 16 pages of other stuff including: a letter to George Orwell, an interview with Huxley, and some other crap I didn't read. Not yet anyway. I needed a break.
Important? Yes, I think it is. Fun to read, or even well written as fiction, not so much.
