The Very End
I've been all over this board looking for anyone who feels the same as I.
I heard heavy, deliberate footsteps approaching Bob at the end of the movie. Didn't sound like Nadia. Reminded me of the footsteps approaching Marv's car. I think Bob is shot at the end. The whole movie is very deliberate with its story-telling. Reminds me of a David Mamet film.
It sucks that there's an ample amount of argument about sociopaths vs psychopaths, and vitriol over poor grammar or spelling.
