It was okay but he really laid it on thick with the "I can't describe how scary this thing was, but trust me, it was really scary" stuff, every chapter started with about a full page of it.
I'm not really a horror guy so reading Lovecraft isn't some big ambition, but I read the first few short stories in the collection and actually really enjoyed them. Also he's good for the vocabulary.
I'll probably read at least the second two Dune books. Basically everyone seems to agree the series drops into the toilet, the question just seems to be over which point.
