I mean there are some things in the script I like. Such as the dig at M Night. I actually loved how they straight out call out Rob Zombie and Michael Bay by name for "****** remakes."
But there is just too many pop culture references, the worst being how Williamson keeps praising the '90s horror era for "giving away the rules" and causing them to make so many remakes today because the post-modern '90s gave the game away and forced Hollywood to go back to square one. While there is some truth to that, it is just self-aggrandizing ego-stroking on his part as he wrote most of those '90s meta-horrors and it feels like Scream has its head up its own ass.
And beyond that, the opening kills are off-screen, Sidney is just very unlikable and bitter towards Gale and almost all the characters which contradicts the "finding inner-peace" and strength angle Williamson introduced her with and she has in the final film. The reason Charlie's betrayal of Kirby works so well as he pines for her in the whole final film and then when she "saves him" he stabs her twice in the stomach with a butcher's knife. Instead, they're just out-triviaing each other the whole script here and he only is pissed she got the questions right. Plus, there's no Stab-a-thon which was great. And then the lack of a resolution?
Eh. It is about 70% or so of the dialogue in the final film and it is the basic plot. Williamson brought Scream back with a vengeance with his story and most of the dialogue, but however difficult Bo Weinstein may have been, the film was better after the rewrites in the finished version.
