I don't want to be too critical, but it would have nice if you moved locations on the Platform. Would also liked it if we could see which side of the Platform is "Brooklyn Bound" & "Manhattan Bound".
An excellent video. I always find it quite fascinating to see the variety of people using trains. Purely for my own amusement, now and again I take a few pictures of buses and trains in my local area here in London UK using my cheap camera phone.. May I ask what kind of camera you use? And do you ever get any objections from people being filmed?
