Documentarian Michael Apted filmed a bunch of kids when they were seven years old for a British TV “programme” named 7 Up. He has returned to talk to these kids every seven years since, this year being their 49th. In past installments, Apted and his participants haven’t fared so well, and at a low ebb in 42 Up only featured 11 of the original 14 participants. This time 12 are back, but 49 Up takes a further critical turn as some of the participants implore us to rethink the entire series itself. Surprisingly, it ends on a very quiet note, just a sober splicing of images from then and now with nothing other than our memory of each as a commentary. I have seen most of the rest, and this is the most memorable installment to date. If the series ends here, it will go out with a reflective whimper. Apted’s series will be remembered culling universal truths from this range of largely everyday biographies.
