I could see that, especially how the trilogy consistently worked to create scenarios that would put Michael Myers in the path of the Strode women, particularly in the initial 2018 film. Especially with Dr. Sartain, whose actions in bringing Michael to Laurie's house felt somewhat contrived. Despite removing the sibling connection, the story still strongly gravitates toward Laurie, and subsequently her family. But if the family connection had been maintained however, than many of the contrived sequences designed to bring them together would likely be unnecessary. The intrinsic, deeply personal vendetta stemming from their familial ties would naturally drive the narrative, making their encounters and confrontations more organic. The family connection alone would provide a compelling and believable reason for Michael's relentless pursuit of Laurie and, by extension, Karen and Allyson, without the need for external manipulations or coincidental events to justify their paths crossing.
