It's inevitable that an Artist will reflect his age. For better or for worse. His theme is the collapse of the nuclear family and the nostalgia for said nuclear family. The dissastifaction of one generation with another that you speak of has been around since Classical times. Boomers don't like Gen Xers either.
The thing that makes classics classic is that they speak for all time about the human condition. Better still are the cultural messages of Western civilization that uphold God, man and the artifice of government. There is no need other than the ego of directors to 'update' classic works or shed the dim rays of the time on the perfect work of past ages. This is the slight of hand artifice of those with nothing to say but with the technical means of crafting entertaining illusion. Spielberg does reflects his age - a vapid and self serving one.
The WOTW movie still sucks, but I believe we have made some progress in defining Spielberg and his 'message' for what they are - nothing.
