I've been meaning to pick up Dark Corners of the Earth but I didn't know if it was worth it? I remember I saw that movie Dagon a really long time ago on tv when I was like 12 or 13 and it really creeped me out. The whole Cthulhu mythos gives me the chills. haha I read Dreams in the Witch House late one night and was so creeped out by it I didn't sleep at all that night. HP is the only writer that has ever been able to actually scare me.
This site has a lot of HP stories for anyone whose interested:
the Complete works of H. P. Lovecraft
Also anybody seen this movie?

It's pretty new even though it's a silent b&w movie. It's the best lovecraft related movie I've seen.
