Whoever decided to use a wax dummy at the end is a genius and deserves every amount of praise he/she might receive.
That facial expression has haunted my dreams for years.
I skipped right to the end, saw the ending entirely devoid of context, and now I feel like I'm going to turn around and that face will be there.
I even google imaged searched for the mask so I could see it not on a face, just so I can sleep tonight. That's a hell of a goddamn scene. I haven't felt like this since I was 12. Five stars of fuck you.
