Dunno why they bothered. The original was a true original, the second a washed up version and the third was hacking away at the first but got lost. Now this seems like it is desperately trying to sell us that something new, original and unexpected is going to happen. The problem is, Scream wised everyone up to it's rules and now no-one is going to get caught.
The only real question people will ask is whether or not Sydney dies. But eleven years after the last film, does anyone really care?
And nice job on the guy cutting the trailer. You can see practically everyone who is going to get killed in it.
