Hmm, well I think that the worst one I have read is ehm, hmm, terry Brooks so far, but however I think that he is far from the worst author there is.
Tolkien, you are almost executed if you say something bad about him, but IŽll do so anyway

Toliens books are actually crap except from Lord of the Rings. they make little sense and have a noncommital tone to them, i wont go into Hobbit since I have only read that one in swedish and yolkien had the good sense to refuse to give Lord of the Rings to a publisher for swedish if he didnŽt get another translator..
Well, ok, to be fair, he is an excellent writer, though he is a very uneven storyteller..
Michael Moorcook and the books about Elric are well, not great but entertaining but you are easuily boored after awhile, nothing new..
OK, Terry sorry, you came out at the bottom of this!
