It's not my favorite genre, though often when horror elements are added to other genres, they add a good bit to them. I have no taste at all for slasher horror, or anything Saw or Hostel. Silent Hill was ok, and probably the creepiest recent movie I've seen was I Am Legend. The sci-fi/horror Alien movies are favorites, too.
One of the more interesting horror writers was Lovecraft, he who brought us Cthulhu and his ilk. While not matching King or Koontz in his writing volume (which may be a good thing), his stories did have some interesting elements, including glimpses into realms that are essentially other-dimensional, where our laws of physics are trumped by others, where the lines and angles of structures just don't behave like they do in our world.
Reading Burke and Taylor's "A Heretics Guide to Eternity" felt a lot like that. Attempts to find reason and sanity are too often lacking, and one is left trying to make sense of...well...what???
For example, consider these two statements.
One of my other earlier titles for this book was I'm a Universalist Who Believes in Hell.
And a couple of pages later.
I may be a universalist,...but I also believe in Hell. Do I mean a place filled with fire, brimstone, and flames that burn bodies forever in eternal torment? No.
So, he's a universalist who isn't a universalist, who believes in Hell but doesn't believe in Hell.
While you're making sense of that, I need to go feed my Puppy of Tindolis.
