I feel like I'm kind of burnt out on Scifi/Fantasy, or fiction in general. It used to be that the only fiction I found interesting were scifi/fantasy/horror; now I'm just bored.
The only Asimov I will read is the short stories. I guess the Big Ideas aren't big enough to take up all those pages, but his short stories work much better. Same with Clark, except Childhood's End is ok. I enjoy Larry Niven short stories for the same reason--brevity. Many Heinlein books are very good, but many are also corrupted by his horny-old-man-phase. Ender's game was good because it was short, and it taught me never to read SciFi sequals if you thought the first book was good. Neuromancer is unbelievably good, but Neal Stephenson's only (very) good book was Snow Crash, and that in a Tarantinoesque, snack-food way. The other Stephenson books have been letdowns. I ritually burned Michael Z. Williamson book that I had. I'm not sure that anyone is writing modern Scifi that is decent and I'm out of ideas for old SciFi to explore. Any suggestions as to further reading would be appreciated.
Oh, and I thought Dune (the original Dune) was probably one of the best books I've ever read. I enjoyed it immensely, so I will never read the sequals.
