if we're throwing around big names i'd like to hear Clive Barker. in college, my two big horror authors were Barker & Lovecraft. Lovecraft does a good job of capturing the vast strangeness of our galaxy but has crap characters and Barker really evokes the horror of the human condition but overall villains are usually mundane. later, once i got my head out of my ass and started giving pop culture authors a chance to stand on their own merits, i also added Stephen King to my favourites.
i'd like to hear one solid story unless there's a way to link several smaller stories into a narrative. if you do go with several flash fiction pieces then Barker's down, satan! is particularly strong. it's being made into a movie though so the rights probably aren't available.
blech, another Barker movie. they're so, so bad. nothings that's even ok since the first hellraiser.
