Query: Good Driller Thriller

Driller Killer is about a trouble man who picks up an electric drill and can't put it down. First, he takes to the streets and starts killing off homeless people. Then he starts killing those he believes have wronged him. I will say that the first half wasn't that great. It's not much of a horror movie at first, but things really pick up at about the halfway mark and it becomes a gory slasher flick. And a good one, too.
