Sci-fi and Fantasy can be really excellent genres. However, they're also chronically flooded with really, really poor quality or overwraught and sprawling series. I rank Dragonlance right down there with Danielle Steel novels.

Try some Kim Stanley Robinson, or go for the classics like Bradbury, Clarke, Ellison, and whatnot.

I don't really read sci fi but fantasy books are about the only thing (besides text books/news) I DO read. ITS BRAIN CANDY!! definately a release from all of the political science banter I have to read all the time.

I enjoy some fantasy/ sci-fi. books. However, some seem to be very, very repetitive. You should read Ender's Game and its sequels by Orson Scott Card. I would also recommend Shade's Chlidren and many of Garth Nix's books. I don't thin there is anything wrong with reading these books as long as you know they are fiction and nothing else.
