Working my way through a Lovecraft collection and it's confirmed what I suspected for a long time - he is my favourite horror author. Weird fiction just does it for me - the combination of horrifying occult lore and sci-fi, all smushed together to make us feel terrifyingly insignificant.
BUT, I ask you, what are your favourite Lovecraft stories? Though I'll always have a soft spot for Call of Cthulhu, I think The Dunwich Horror clinches it for me.
