I can provide some general insights into why a character like Michael Myers might be portrayed as weak in a horror movie.

In general, horror movies often rely on a certain level of tension and suspense to keep audiences engaged and invested in the story. One common way to create this tension is through the use of a villain or antagonist who poses a significant threat to the protagonists or other characters in the story. This can be achieved through a variety of means, such as giving the villain superhuman abilities, making them unpredictable or mysterious, or making them seem nearly invincible.
However, as horror franchises continue over multiple movies, it can become increasingly difficult to maintain this level of tension and suspense. Audiences may become accustomed to the villain’s tactics and abilities, or may simply become desensitized to the violence and scares. Additionally, the filmmakers may feel pressure to constantly up the ante with each new installment, which can lead to increasingly outrageous plot twists or actions on the part of the villain.
As a result, it is not uncommon for horror franchises to eventually reach a point where the villain is portrayed as weaker or less capable than they were in earlier installments. This can be a way to shake up audience expectations and create a new sense of tension and uncertainty in the story. It can also be a way to explore the character in a new light or to bring closure to their story arc.
In the case of Michael Myers specifically, there are a few reasons why he might be portrayed as weaker in “Halloween Ends.” One possibility is that the filmmakers are looking to explore a different side of the character. Throughout the Halloween franchise, Myers has been portrayed as an almost supernaturally powerful force, capable of withstanding immense amounts of physical damage and continuing to pursue his victims no matter how many times he is shot, stabbed, or otherwise injured. However, this portrayal can also be limiting in terms of character development, as it does not allow for much variation in Myers’ actions or motivations.
By making Myers weaker in “Halloween Ends,” the filmmakers may be able to explore new aspects of his character. For example, they may delve more deeply into his psychology or backstory, or they may show him struggling to overcome a new obstacle or challenge. This can make the character feel more multidimensional and interesting, and can also create new opportunities for scares and tension.
Another reason why Myers might be portrayed as weaker in “Halloween Ends” is simply because of the constraints of the story. Without knowing the specifics of the plot, it is impossible to say for sure, but it is possible that the filmmakers have chosen to tell a story that does not require Myers to be at the peak of his powers. Perhaps the story takes place many years after the events of previous films, and Myers has aged or become less physically capable. Or maybe the story involves other characters who are able to outsmart or outmaneuver Myers in ways that previous protagonists were not.
Finally, it is worth noting that the portrayal of Myers as weak in “Halloween Ends” does not necessarily mean that the movie will be any less terrifying or effective as a horror film. While the character of Michael Myers is certainly an iconic part of the Halloween franchise, there are many other factors that contribute to the success of a horror movie, including the writing, direction, cinematography, and sound design. Even if Myers is not portrayed as an unstoppable killing machine in “Halloween Ends,” there are still many ways that the filmmakers can create a tense and suspenseful atmosphere that keeps audiences on the edge of their seats.
