People complaining this movie is monotone and quiet really have no idea what the point of the movie even is. They head first into the point and still can't fathom it.
My only critique about the movie is there's no way in hell a cat can stay that quiet unless it mute or something. Also the chess pieces outside were all on the board even after the heavy thunderstorms and bombing. Unless someone had a quick unfinished game before Sammy got there, it makes no sense; the pieces should be on the floor at the very least.
