I didn't have an issue with the Michael/Laurie familial connection at all. I was actually a fan of it in Halloween 4 with the introduction of Jamie Lloyd and liked it being the driving force of H20 but it got kinda ridiculous with Halloween 5 and then Rob Zombie just took the concept straight into the dumpster with his two shytty movies.
So I am actually eager to see a return to The Shape as a random serial killer without a blood vendetta as his sole motivation.
My only issue with it, actually my main issue with it and that issue has affected the entire series, is it makes Michael less scary. We've had this discussion before but he's a shape. that's it. He's evil. Him being related to this person he's killing makes it personal and something I can sort of connect with. Not trying to kill relatives lol but it makes Michael more human. Michael ain't human
