Aah yes I definitely see where you are coming from there, and I do agree with you. The fact that Michael Myers, for example, was never 'explained' made him all the more terrifying. If we had found out that he was beaten as a child or something he would have lost his chill. But, with Creep, my problem was that it began to explain, but then seemed to trail off. I think that if they were going to explain Creep at all, then they should have focussed more on this, or simply left him as a mystery. They made a kind of half-assed attempt at an explanation, which weakened the story considerably. If this explanation had been filled out then it would have given more depth to the Creep character, or the easier method would be to, as you say, leave out an explanation entirely.
