Lovecraft is often portrayed as the successor to Poe in the genre of short horror stories, but after reading Lovecraft's stories (and editing Edgar Allan Poe Annotated Short Stories), I can tell you that he is no Poe. Lovecraft is much less a pioneer than Poe in both character and Gothic atmosphere. Lovecraft gave us the Cthulhu Mythos of cosmic horrors, of ancient horrors lying dormant, of horrors that transcend space and time and dimensions. He holds his rightful place of high esteem in horror literature for this and must be remembered as a result.
Lovecraft studied Poe. He worshiped him and rightly so. He wrote "The Outsider" in apparent homage to Poe. But the similarities stop there. Let's not forget that Poe wrote 80-100 years before Lovecraft, too. Lovecraft also used the word "foetid" more than any other writer that has ever lived by a factor of ten, but that's another article. Plus, he looked downright creepy, too. Although Lovecraft was no Poe he gave us some great stories and these are my favorites:
"The Call of Cthulhu"
"The Colour Out of Space"
"The Dunwich Horror"
