I like this too. I've watched it several times, looking for reasons to criticize it, but I can't fairly do it! It's easy to say it's sentimental, or Luddite, blah blah blah. But the truth is sometimes difficult for us to see. It really is well done.
The other day something really disturbing happened - not once, but twice. On a bus I overheard the driver muttering to himself audibly for about 20 minutes between announcements, which were all said very calmly. It was the first time I've ever heard someone at their job talking to themselves audibly with other people nearby, for such a long time. I kept thinking he'll stop any second, but he didn't. The one thing I could make out was the word 'pontificate'.
On the return trip, believe it or not, a lady security guard got on and she did the same thing, for another 20 minutes. Among other things she said 'People in this city are stupid'.
Both times I looked around to see if anyone else noticed, expecting to see at least one or two others because each time it was crowded, and there was no other loud noise - but no one seemed to notice. I guess they thought what they overheard was one end of a conversation. But both times I looked for wires or microphones and saw exactly none on either of them.
The thing that was so disturbing was that both of them seemed otherwise to be perfectly sane. And they were both in uniform. They were coherent, but angry to distraction.
The downward turned heads is really disturbing. People don't seem to care enough to pay attention to their surroundings even to keep themselves safe.
