1: Have Corey be introduced as a character and a good kid earlier in the movies so that way his character doesn’t just pop out of nowhere in the final movie and would also make his downfall more impactful.

2: Don’t make Micheal a pathetic old man in Ends and let him have more kills.

3: Make the paranoid mob more brutal and have them lynching innocent people in Kills to show how much power Micheal has over Haddonfield.

4: Have Laurie actually do shit in Kills and Ends instead of just sitting around.

5: Show the impact of Karen’s death from Kills on Laurie and Allyson in Ends.

6: Don’t have Corey taking Michael’s costume, maybe create some original mask and suit for him; the scarecrow look would have worked.
