I rented the movie and did not like it. The jokes were wasted, it felt like a Troma film (even some of those have been funny). It could have been better - I think the main objective was how to make scenes from "Scream1","Scream2","I know what you did last sumer","Matrix","Sixth Sense" appear. They were so engrossed in this they forgot that there was a movie to be made too.
