I'm seeing all these people calling out for Lovecraft and Cthulhu, and it makes me sad, because I doubt most of them have even read his works. Cthulhu was a small part of the whole mythos. Beyond that, dude was pretty damn racist. True, it would be a product of his time, but still. I also have some doubts about the callers for Douglas Adams having read things like the Dirt Gently books (and by God they should).
Now, someone who not only deserves it, but needs it? Robert Jordan. Why? Simple, his work was unfinished. He never completed the story. Yes, Brandon Sanderson will complete the wheel and theres nothing wrong with his writing, but tarnations if I don't want to see the man who started it, finish it.
