Ok, so as most of you know, in the world of Wes Craven's Scream, Jason Voorhees, Freddy Kruguer, Michael Myers, and such are all fictional. So it's alright that during the first Scream movie, a group of people are watching Halloween. No problem there. But in Halloween: H20, supposed fiction from the Scream universe, someone is watching Scream 2.
This means, in a world where it's entire existence had been deemed fictional, someone can view the very thing that states and more or less proves it is fictional. It's stupid cross promotional crap from Dimension Studios.
