Valid points, but I'd say that Rob Zombie and myself didn't miss the point so much as dismiss it. Once again, I do love the original Halloween, but even watching it for the first time, when I was probably about six or seven myself, it seemed weird to me.
Sure, Michael is presented as a motiveless killing machine; that is, among other things, the function of Dr. Loomis in the story. It just always struck me that Loomis was wrong, and that just because we weren't informed of Michael's reasoning and motivation, doesn't mean he doesn't have them.
It appeared to me that Zombie was aware of this too, as he makes a point in his film of Loomis presenting the "pure evil" theory (and even writing an exploitative paperback about it, as a real shitty doctor would likely do), and then showing him to be wrong.
True enough, it's hard to separate the original Halloween by itself from the canon of the series, but even by itself, it was scary, but I never doubted his motivations. The sequels just gave me fairly poorly executed reasons for it. Zombie gave me better ones, and that, I suppose, is the basis for my preference of the remake: I've always been interested in the origins of dynamic and interesting characters (hell, my favorite character in Huckleberry Finn is Huck's father).
I know not everyone agrees with what I enjoy, so that's likely a lot of what splits people over this.
That said, I'm still more attached to Friday the 13th as a series than any individual Halloween.
