If Dead Man’s Shoes were just a low-budget slasher movie it would still be head and shoulders above the rest. Showing us victims of the killer that we slowly come to enjoy the company of, despite their obvious flaws, before whipping the carpet out from under you.
But it is first and foremost a revenge film, we see the thoughts and machinations of our “slasher” who follows through with his plan right to the end. Getting to everyone who caused his pain. Everyone.
