I have to say, I love anything creepy, scary, horrifying, demented, crazy, and well, you get the idea.  Recently, I've discovered an idea for a good suspense/thriller story.  I've written out part of the outline, just basically a summary of the plotline.  I am a little stalled though; I'm having trouble deciding if I should add a monster or something supernatural, as the antagonist, or if I should add something that could be possible, such as a new creature humans haven't discovered.  I really enjoy the idea of something supernatural, yet it seems cliche to me.  AH! It's very irritating trying to figure this out, the ol' famous saying, "To be or not to be, that is the question.."
