I've been wanting to watch Terrifier and its sequel for a while now but it seems like I only want to watch it when I can't commit to watching a movie and forget that I want to watch it when I can.
But the last time I was able to commit to watching a movie, I decided to round out my revisitation of the Phantasm franchise with the last film in the series:
Shot in secret between 2012 and 2013 before getting released in 2016, this final film in the franchise finds Reggie wandering the desert after the events of Phantasm IV and soon the film cuts between a timeline in which Reggie is in a hospital with dementia, implying that the prior films are all in his head, and another where The Tall Man has laid siege across the world, turning it into a desolate hellscape of death and destruction.
It seems to be a somewhat definitive end to the story, but at the same time leaves room for a follow-up.
As for me, I actually came up with an idea for one, as one can read
here. The TL;DR is it's an alternate timeline where Jebediah Morningside died before building his dimensional fork but someone years later builds it and becomes that dimension's version of The Tall Man, thus leading a pair of siblings against this variant before he kills the living and enslaves the dead in their small town. And since the series has touched on the idea of the multiverse, it's possible to have various Tall Man variants from different locales, time periods and even cultures.
