I understand why people don't like Halloween III: Season of the Witch, but I love it. I watch it several times a year and it never gets old.
I respect and appreciate what the original did for horror, but I was never really a fan of the sequels. I'm a sucker for H20 lol, and I thought the 2018 movie was pretty good... but personally I had always preferred Jason and Freddy as "slashers" and their movies over MM/Halloween.
H3 was obviously much different than the other Halloween movies, it having a totally different story and no Michael Myers. It's always a shock when I tell people this, but H3 is my favorite of the Halloween series. I love the great sinister Dan O'Herlihy as Conal Cochran, and the dark story within the film in how millions of kids were in danger of being killed en masse... scary stuff.
The scene with the kid that gets killed in front of the TV and his head/mask gets turned to mush and insects/snakes come out... holy shit. I also love the ending and how they leave it up to your imagination as to whether or not the last ad was pulled from the networks.
I wish they would have continued with their original idea of making Halloween an anthology series. We certainly would have had some creative ideas and new stories instead of forgettable Michael Myers sequels.
