This was shown in their decision to ignore every single sequel in the series, as they wanted to be the only sequel to John Carpenter’s 1978 original.
As David Gordon Green explained to Vice during a paired interview with his fellow filmmaker, he and Danny McBride had a clear vision in mind when it came to the Halloween sequel they wanted to make.
Such a choice not only gave audiences something new and fresh to look forward to, it gave the series a new lease on life; one that Carpenter clearly appreciated, given his ultimate involvement with the project as a producer and composer.
Considering his history with the franchise only extended to writing Halloween II and producing Halloween III: Season of the Witch, it’s not a huge shocker that he was okay with the bulk of everything else being junked.
