I just started to get into Science Fiction, and am surprised how much I enjoy them. The format allows for the exploration of deeper issues of morality, humanity, society, and spirituality that would be harder to explore in modern fiction without it being pretentious. Even so, I find modern fiction extremely petty and vain.
This is
exactly the same reason I read - and love - high fantasy. I don't find the same fulfillment, however, out of
reading sci-fi. I prefer my sci-fi to come in doses of TV and movie (i.e. Star Trek), however, I thought that Ender's Game (Orson Scott Card
is a master) was truly brilliant - having such a powerful message - and I agree with it being required reading in schools (as it is, in some schools, in the States). High Fantasy remains my genre of choice, consistently, because of the afore mentioned exploration of REAL life issues. I even wrote an article about it a few years back entitled,
An Essay of The Heart - Why I Read Fantasy. In that article, I examined the worth and message of the books I am drawn to over the modern - and usually disgustingly jejune - fiction novels out there that people seem to mindlessly feed upon, and get sick on, like too much Halloween candy. I used to manage a bookstore, so I had quite a while to observe my consumers "diet" - a foolish diet, for the most part, a lot of the time, in my opinion.
It does not surprise me to hear that you find such substance in the novels you have mentioned; they are ever more than "just a good story"; while they
are entertainment, they are also so much more. Keep reading...and adventuring. And, let me suggest to you, that if you are finding such enjoyment from these books you might also find such in my favourite genre as well...for the same reasons.
