"I suppose what makes Lovecraft both good and bad is the fact that he was an obsessed writer. And this is also the reason that so few of the works in the Lovecraft tradition have touched the same level of imaginative power. August Derleth or Robert Bloch can capture the Arkham atmosphere and style excellently, but it doesn't express their true centre of gravity as writers. [...] This explains why Lovecraft has remained unique, in spite of the number of writers who have been fascinated by his mythical world and by his style. He created the Cthulhu Mythos out of inner necessity."
