10 Things You Learn Rewatching Halloween 4: The Return Of Michael Myers (1988)
4. The Larger Scale Doesn't Work
The film's script begins to lean a bit too heavily on Michael's more supernatural abilities as the film carries on, with it becoming an outright crutch in the second half.
While Michael was always a "force of nature" in the previous films, he was pretty much located in one area. In the first film, it was the Wallace and Doyle households. In the second film, it was Haddonfield Memorial Hospital. But in this film, Michael's playground is expanded to the entirety of Haddonfield.
As a result, the script spends a lot of time having him be practically omnipresent. He destroys the power plant on the outskirts of town and then is able to be stalking Rachel on suburban streets mere seconds later. He has the time and resources to murder the entire police force, while also visiting the Carruthers household at the same point in the plot.
This deflates the film's tension, as seeing Michael locked in a room doesn't exactly mean anything after we've seen him seemingly teleport across town. It also dilutes the character of Michael Myers himself, making him less of an actual character and more of just a tool in service of whatever the screenwriter needs.
