Never seen H20
I'd rank them
Halloween
Halloween III
Halloween II
Halloween IV
Halloween V
Rob Zombie's Halloween
Halloween 2018
I thought the first time I watched Rob Zombie's Halloween II i liked it but I watched it last year when I picked up the blu ray and didn't enjoy it as much as I thought.
The same happened first time I watched Halloween 2018 I liked it but then Dem pointed out a few things and when I went back and watch IV and V I just thought wait one minutes that was just these combined so it went down in my rankings. But it's a masterpiece compared to what followed.
