Jordan - First four books are amazing, the next billion suck ass. Book 10 actually had three chapters on how the characters dealt with an infestation of weevils in their wheat! Characters were all idiots and by the end of the last book I read (11 I think) I was actually rooting for the dark one to wipe them all of the face of the earth.
Song of Ice and Fire - Excellent! Characters that have depth and plots that make sense. GRRM also has a good series of books called Wild Cards about how superheroes would actually work in a realistic world which I also like, and his SciFi stuff (Tuf Voyaging) is great.
Hyperion - Read the first book and liked it but then split with my ex and she took the rest of the books. Is it worth picking up the others?
Any one read Vampire$ or Armour (same author)? Try them, you won't be disappointed.
