Worthy but flawed
Literally filler. When they expanded the new Halloween series to three films, they needed some extra padding, which is basically all Halloween Kills is. There's no real plot, no obvious ending, just Myers running around, killing people. That's not necessarily a bad thing, but Green just isn't the man for the job.
Michael Myers survives the fire from Green's first, killing a bunch of firemen while he escapes the burning house. He is on the loose, planning to return to his old home, but the road is long and in between he'll find many people on his path. Some of his old survivors are banding together to track him down, catching him is still pretty much impossible though.
The problem with Halloween Kills is that Myers isn't very formidable. He kills a lot of people in rather unadventurous ways, and that's that. He has lost a lot of charisma in Green's series, and that used to be the thing that set him apart. Performances are pretty weak too, but at least it's slightly better than the 2018 version. Not great, but acceptable filler.
A rather poor attempt to sequel-reboot the Halloween franchise. Green fails to build up the needed tension, the acting is subpar and the film often drowns in references to the original. Too much pandering to the old, not enough identity and balls to be its own thing. Time for another reboot I'm afraid.
