yeah I responded though It didn't seem to go through, possibly because of outside forum links.
Lovecraft is not at all like Poe.
Poe is more like a classic horror writer while Lovecraft is the Father of modern Horror (compare to Gullivers travels or Dickens novels to Tolkein father of modern fantasy)
there are some classic horror stories in Lovecraft
I recommend The Walls of Eryx, coauthored with someone else its based on Venus and it a horrific sort of SciFi
in addition The Colour From Outside Space is my all time favorite (and a great introductory story to Cthulhu Mythos, which is not necessarily always to do with Cthulhu but is a general term like say a story of Middle Earth, or a Forgotten Realms book)
