Sorry Ray, I don't relate to this at all. Negative killer talk set to music is just not my thing.
(I'm not into horror films either.) I tried but I didn't make it past halfway of the short one - just too far from my taste so I can't help you with any meaningful critique. All I can say is since you use a mastering engineer instead of diy, I don't think overall sound quality is an issue for you so go with your gut. As popular as horror is, I'm sure there's plenty of audience out there.
