I've seen them all to date. Age 7 most of them were very endearing and in the case of the two Barnardo boys so poignant. Neil was probably the most bright eyed and bushy tailed of all of them, so it was quite upsetting to see his downward trajectory over the years, but I gather his situation has improved. Aged 7 contrasted sharply with the teen years, where some were the embodiment, as indeed we probably all were, of all that teen angst, although Tony appeared at that time quite self assured I thought.
They are pretty much my age so for me it catalogues quite well the aging process, I expect some of it will touch on possible aches and pains and health tonight. Sadly one of the 3 London girls died a couple of years ago a sharp reminder of our own mortality
I do understand why a couple of the original participants have dropped out, signing up for such a documentary at age 7 is hardly making an informed choice and it is quite an intrusion having the eyes of the nation observing just how life has panned out. Nevertheless fascinating viewing quite groundbreaking before all the ghastly reality shows took hold and shaped some of the future generations behaviour in playing to an audience which does contrast with the "7 up" generation who appear to have remained true to themselves.
