For me the fact that this is kinda "off the wall" and silly makes it an dig at the Slasher Movie genre. They're like a teenagers wet dreams (the films). All gratuity and the like, and this seems to be mocking that.
I'd have to side with Calvin on the, change position and the lack of description for panel after panel.
The story really could be a nice little short and a good artist who doesn't mind the "change position" panels in there might have a field day with it. You taught us to arm the artist with the descriptions that will stop him asking questions. A little too much freedom for him in this story.
