For SF, Heinlein and Asimov were far, far above their peers - no one since William Gibson has done much that doesn't seem to be a warmed-over remake of what has gone before. And too many very good SF writers (like Kim Stanley Robinson) have been bitten by the "Green" bug and have taken to cranking out Al Gore speeches disguised as fiction. Vernor Vinge is one writer I still like.
Fantasy has been dead for a while - killed by too many feminist witch parables, LoTR clones, and Robert Jordan clones of Dungeons and Dragons clones of LoTR clones. :)
Really? Hard to believe. If the book is written well, it is interesting to me. Even some of my kids' books are fun reads. Angie Sage and herSeptimus Heap series just came out with her 5th installment for young readers. (but) I am also looking forward to the next Dresden Files too.
There is a lot of repetition in both genre's. That's why it is good to get opinions. (IMHO)
