First off, I just want to say I was alerted back here due to the thread being overrun by Halloween 6 explanation theories, and ultimately, a request to get the H6 review up. I suppose I can get it posted soon. I've completely forgotten about this thread until now.
Now, I won't dig too deep into the H6 theories simply because I don't want to step on anyone's toes. The thing is, I understand it perfectly. It's just not LOGICAL. So I'll explain the way I look at it. You have a whole film building up the transference of the thorn curse, being watched over by the Cult of Thorn. That works perfectly fine until the cult is revealed to be a cover up operation.
As I reach this point, I wouldn't say Wynn was trying to "control evil", as it appears (to me, at least) that he was trying to create an army of "super soldiers" by cloning Michael's child, which would surely be in possession of Michael's invincible genes, right? So that also tosses out "Stephen just being there to be killed." In the producer's cut, definitely. In the theatrical cut, he's there to be cloned. It's simple enough, it's just a complete Moron convention. I can understand trying to tie the gap together and I have no problem with H6 theories personally, the problem in doing it is that you're trying to tie together ropes that just don't reach, if they're even there at all. It doesn't work. If you want it to make sense, anyway. It never will.
