They recycled the original Carpenter's H4 script for this movie...
*SPOILER ALERT*
This is taken from the Halloween 4 trivia:
Series creator John Carpenter wrote a treatment for this film that had a more ghostly psychological approach to the Michael Myers mythos. It concerned the town of Haddonfield and what effect the events of the first two films had on its citizens.
This was obviously rejected, it also involved Tommy and Lindsay, I can see why it was rejected, it was a complete mess!
I had high hopes put on this movie, the 2018 film has it's flaws but it is good at revitalizing another Myers alternative timeline, but the plot for this film doesn't hold up in the present timeline at all, they make it look like Haddonfield is another Derry (from Stephen King's "It"), situated on an isolated island or another dimension separated from the real world and filled with mindless rednecks; you see worse things now than a masked serial killer who hunts with a knife, all the town is aware of Michael Myers being on the loose, it's all over the news and they make it look like they lack of police, national guard or FBI in 2018 ffs, they also have just one hospital and it looks like Michael himself kills the people and takes them there personally (the bodies are found really fast), the town glamourizes his wonderful killer in every scene, the dialogue was all about Michael being a glorified superstar, they repeat the same dialogue we have heard in every previous film in case we forgot who Michael Myers is, it was just unrealistic as it gets. They also relied on making the old characters repeat their lines from the first film and filming the same sequences just for nostalgia fan service purposes (the car scene with Marion for example).
I loved Myers in this film, he was brutal and kept his mannerisms, he was absolutely terrifying and scared the shit out of me everytime he was on screen, they really cared on every detail about him, they explore Michael as a sick sadistic killer we haven't seen before (except on Halloween 6) I liked the '78 scenes but they felt pointless with the subplot of the sheriff stuff that got nowhere in the film, Laurie was more annoying and pointless this time than in the previous film, the characters made really dumb moves and stupid decisions for the film to be placed on 2018, Karen was the only good character in the movie, the one that represents the viewer.
Sorry for my english. share
