I've only seen "28 Up" and "35 Up". Those were fascinating interesting films, dealing with all types of people and all types of issues in their lives. At ages 28 and 35 people are trying to see where to go what to do, etc. By 42 they're all married or bringing up kids. So the whole movie is about dealing with marriage and kids. Fascinating if you're one of two--dull if you're not. It started off well enough, but it seemed to keep rehashing itself (if I had heard ONE more comment about how hard it is to make marriage work...). About half of it was interesting, and it always a kick seeing these people literally grow up, but it's run it's course. Let's hope there's not a 49 Up!
