Well, since this is a spoiler forum, I'm just going to come right out and say I fear a sequel to this film. Of all the Halloween films, this one ended such that a plausible way to bring him back really isn't there; every film has stretched what he can survive, but we're led to pretty much assume that Michael's head is blown wide open when Laurie pulls the trigger, doesn't leave much room for sequel power when your head's split by a gun, and whatever manner they could come up with to make him come back would just seem cheesy. Halloween 4 was believable because Michael's more than human, so to survive flames was acceptable, as was the multiple times he came back from gunfire. Resurrection even did a decent job of getting past the fact that his head was severed off in H20 by writing that he swapped out with a guard, you could buy it, but I don't know what you could even hope to get your audience to accept with this one.
