I have run this at a couple of con and store events and each time it's run it's fantastically enjoyable. The sandbox format allows for quick on the fly thinking as a GM and a player. I think that if you preface this adventure with the phrase "think 80's slasher flick" and have them pick a pre-genned character - the magic will be from the players willingly fall into their respective roles.

Worth it to run it and play it!
