I assumed the second "half" took place in the present day. If it took place in the 90's its just another stupid, pointless element to the piece of crap we call "Rob Zombie's Halloween."

The REAL question is: If this too place in the 90's, and those girls went to see Scream, and the scene with the original Halloween came up, would it result in one of those horrible things Doc from Back to the Future was warning us about??
