So me and my Son are watching H5 today and a couple questions popped in my head. First: The abandon house, was that supposed to be “The Myers House”? or the house where Michael did his killing in H4? I know Dr Loomis mentions about Michael coming home in H5, but that house is WAY off from the original, it looks more like the house in H4. Second: In H4 were lead to believe that Jamie is the Daughter of Laurie Strode, so if thats the case then why in H20 don’t we ever hear any mention of Jamie being her daughter? Just Curious.
This has been brought up several times I think. To answer the last part of your question - that’s the big bother to some fans: we’re just supposed to forget that 4-6 ever happened, it goes H1, H2, H20 at that point.
As for the first part of your question - I think that’s the H4 house…but y’never know with sequels, man. They may have meant for that to be the Myers house 
It was definitely meant to be the Myers house. If nothing else proves that (“Michael GO HOME!”), look how dilapidated it looks after only a year has passed since the 88’ murder spree. I agree it is completely screwed up, though. Thank the “creative force” behind Halloween 5. At least Halloween 4 had the courtesy to not show the house, rather than give us something far-fetched and way off.
