When it comes to Friday the 13th, Jason, the most hated parts are Friday 5 and Friday 9 Jason goes to hell lol.
Quality varies between Friday movies but part 5 and part 9 are universally disliked, for similar reasons.
And to me, Halloween ends combined the problems that Friday the 13th part 5 and part 9 had lol. ( A different killer besides Michael/ Jason, their killing essence being transfered to a different person,
unnecessary lore. Unnecessary paranormal explanations of evil transferring around)
So Halloween ends wasn't even that original, it felt like it borrowed heavily from Friday the 13th part 9 Jason goes to hell. That was the other problem. It might be an original concept for Halloween to have Michaels evil transfer to Corey but Friday 13th part 9 had already done it ...
