2. The First Two Ghostface Killers Are Revealed.The ups and downs with Billy being the killer and then not being the killer (rinse and repeat) finally came to a conclusion with him indeed being the killer, and the fantastic reveal that there were actually TWO killers. As I’f this weren’t enough, the entire final act has one twist/reveal after another, yet never manages to be ridiculous. That final act, and the reveal of the killers , incorporates the world of horror movies ( and horror movie fanaticism) in a very real way. There are so many movie references in that scene alone, but it never feels like watching a horror movie; it feels very much like watching two actual psychos.
