As fascinating as it can be for many to see the changes in the participants over the years, it can be just as interesting for cineastes to see how the series evolves over time, namely how it has become increasingly self-aware. For example, one person returns to the series after decades away to promote his band while another uses it to continue to promote Bulgarian charities successfully. And I loved the Buzz Aldrin story, by the way. But what I gained this time around was a profound knowledge of how different Great Britain really is, especially how university education is not necessarily a given over there, unlike here in the States. So, maybe the class system is alive and well in Britain, despite one who protests it was never there in the first place, followed by a scene of a fox hunt. This time, the politics is less about the subtext, becoming front and center with Michael Apted even calling out one of the participants for some of his objectionable comments. This is all in the wake of the Great Recession which drastically alters some lives at an age where people would be ordinarily starting to look forward to retirement, just as London takes center stage in the world for the Summer Olympics in 2012.
