What a twist on the classic... didn't know about the original, but the way you've switched up the theme while still keeping the plot element is just perfect. When we see the sign at the beginning though it really does seem like a post-apocalyptic world... jumping into the house, the TV feels like a contradiction to that. How would that work past the apocalypse?! In retrospect I guess it's a clue, or maybe it was always just showing static... but either way you really bring out the emotion here, and the anticipation that comes with the knock on the door. Somber and suitable music to boost the mood, and a great build-up till the end. Nice piece.
