You say that, and sure, it’s reasonable in a quirky B move cinefile kinda way.... but in terms of cinematic legacy, what scene from any latter Halloween sequel is remotely memorable? Or iconic enough to form part of even the nichest horror genre lexicon?
The one where the little kid was evil? The one where they ret-conned that immediately? The one where Paul Rudd is kinda of a weirdo but also the good guy somehow? Or the one where Busta Rhymes drop kicks Michael Myers out of a window on an Internet livestream?
I mean, of course it’s one of the best horror franchises, by default. It’s not exactly a deep field! The Scream sequels are largely not terrible, and occasionally interesting.... and the Saw films are actually quite inventive now and then....but still, all complete fluff in the long run.
