The incest thing and the fact that Michael was used as a puppet meant a lot to me as a change, at H6 he couldn't be controlled and also killed the cult at the end, but on the producer's cut he was like "yes sir(?)" (I hated it) he only fight back at the end with Wynn only to freed himself from the curse.
And that's when all of us has different kind of thoughts when it comes to try and guess what's inside his crazy head xD, I particulary enjoy that fact, when I'm all like "WTF were you thinking when you did that?" The case of Rhymes is an example btw. It was pretty funny xD.
Then you have Richard Curtis had his own version of Michael when he wrote that novel about the movie, I've to say I liked it pretty much. There is explained a better reason for his behaviour and curse about Samhain.
For that reason I don't like how they explained the curse on H6, I prefer to think he just moves around with this rage inside and the other stuff because of a curse, yes, but I don't like to see all that cult around him as if they were like "oh look, there he goes!"
He was a puppet of the cult we wanted it or not at the producer's cut, and he raped Jamie because they made him do it. I'm not a fan of the incest, but I don't care if it had to happen at these movies because I tend to get confused most of the times when Michael does different kind of thing, so it's like putting your hands in the fire for him when you "believe" he's not that messed up xP
As for myself for example, I never thought of the posibility of Leatherface getting into incest, since I saw him kind of horny at the sight of an ordinary woman, but not around his family. (When it comes about Michael, he only tends to behave as a voyeur, and he started it all watching at Judith with her BF) When you have to deal with this kind of characters, there will be always the doubt about which's their trigger.
