As crude and simplistic as this seems at first (dreadful title design, cheap-ass music), I honestly felt more engaged by this short than by Jonathan Glazer‘s Under The Skin, which comes from a somewhat similar place (i.e., an alien life form dabbling in human sexuality). It works because of two elements. One, the sharp knocking on the door with no one found in the hallway. And two, the lights flashing off and on about halfway through. Even the shit-level FX at the end isn’t that much of a hindrance.
