The thing about this one is it really needed a decade or so of development in order to get to the point where it could say the things implied by the review. It needed a decade of horror remakes and post-Scream
self-aware horror movies. Now it's in a perfect position to skewer all of that stuff, and after that's done, what's left to say?
Maybe they should schedule Scream 5
for 2021 and see what happens to the genre in the meantime.
