I agree with those who suggest that sci-fi is a genre which appeals to children. I firts read Heinlein when i was about ten, Children of the Stars
, and thought it was marvelous. I got into sci-fi big time after that. By the time i was in my twenties, though, i was reading less of it. In my mid-30s, i re-read Starship Troopers
, and thought it was awful. I then re-read Farnham's Freehold
, and was appalled to realize what a racist, sexist and elitist creep Heinlein was. Ender's Games
was somewhat interesting, but, in the end, predictable--it was a long short story needlessly stretched into a novel. I read the first sequel (don't recall the title) and was even less impressed.
I agree with FM that much of it is based upon bad science. I understand the appeal, but few of the authors of science fiction are really good authors, and much of the appeal is to visions of either Utopias or Dystopias. I don't think it wears well with time. A very few, such as Asimov and Gentry Lee both write on interesting themes, as well as writing well--most of it is crap, though. Anyone who is fascinated by Orson Scott Card might do well to investigate the man--his message is a blend of his Mormon background (his ancestor was a son-in-law of Brigham Young, and founded the first Mormon settlement in Canada), and conservative politics. The Wikipedia article
states: A self-described Moynihan, Tony Blair, Zell Miller Democrat, Card is a vocal supporter of George W. Bush, the war on terror, the wars in Afghanistan and Iraq, the USA PATRIOT Act, and U.S. support of Israel.
Card is a talented creative writer, although i think he does better outside the sci-fi genre, where he has largely exploited his character Ender. He is also a strong influence for conservatism among young readers. He is also a very effective teacher of creative writing. His views are not to my taste--i find that i despise only Heinlein more than i do Card. Nevertheless, his talent as a writer and as a teacher are not to be doubted--although he has used the former talent in cheap exploitation to enrich himself more than he has produced great writing--but who's to criticize the man making money from his talent.
