Sorry but... no.
Really. Just kindof cliche and predictable. And I'll have to agree, the cat thing was really unnecessary. I think it would have been better if the guy picked up the knife and killed the trick-or-treater. Ever notice how the psychopath trying to kill someone always seems to be invulnerable? How about one who screws up and someone else gets the drop on him and ruins his plan. P.S.: I know the squiggly line drawing choice was a style thing but it's sortof difficult to watch.
