I haven't seen the one due out this month, or the one just before. I saw the others, I think up to 35 Up. I love the idea, but damn, they start recapping so much that by the fourth one, there's like a half hour of new content and the other hour and a half is a rehash, some of which you've seen three times already at that point.
I like the guy the best.
I could have sworn there was a Russian series exactly like this. I've brought it up on here before. I caught one installment many years ago on Discovery or some such. The kids were either seven years old or fourteen, can't remember. I'm pretty sure I didn't imagine it because the only reason I started watching the 7 Ups a few years ago was because I thought, "Hey, this sounds just like that Russian one I saw." But nobody seems to know what the heck it is.
[fake edit]: Google search says it's 7/14/21 UP Born in the USSR. Netflix does not have it. Youtubeing movies is ghetto, but maybe I'll do it anyway. I remember it being better than the US version...
