That's why these new movies were dumb.
Michael apparently doesn't care about Laurie or want revenge in these new flicks yet still stalks her,her family and repeatedly tries to kill her.
The director tried to act like Michael and Laurie being siblings was a dumb thing and what they did here was better when in reality the sibling angle is the only non contrived reason to have Michael constantly engage Laurie and have Jamie Lee Curtis repeatedly in these movies.
Then you get how they treated Michael Myers. He only killed three people in the fist flick on Halloween, yet they built him up like they were including what he did in the original sequels where he went multiple killing sprees/rampages
When you look back on this trilogy, they were really just quasi remakes of Halloween 4, 5 and 6. And those movies WERE BETTER.
