Okay, I'm not easily weirded out, but a Christian horror movie?
There's always been a puritanical streak in horror stories that I've never been comfortable with, but that's an essay for another time. Alls I know is that certain elements of this trailer set off alarm bells. On the surface House looks like another goofy haunted house flick, but I did some research and found that both authors are heavily steeped in contemporary Christian literature and the movie will feature Christian heavy metal.
Alarm bells. Great, something else telling me I'm going to hell.
