great piece of social history

Rating: 9/10 (17 December 2018)

Spoilers ahead. A lot has been said of those last 5 seconds--the look on their faces--that turned....somber? serious? I have two takes on that---first, I think after the smashing of social restraints--ripping away from a marriage and the culture it represented, began to dawn on them--more so Dustin Hoffman---that they were facing a whole different future, and with that came responsibility. So those reflective faces showed their concern for what lay ahead. Just a hint, anyway.
My second take is this: no way was Mike Nichols going to make a movie where they lived happily ever after. That would have been too 'Hollywood'. So he put in the last little hint of seriousness, without ruining the ending--where the camera stops and the bus moves forward.
