7 Plus Seven (1970)

Not as interesting as its predecessor, simply because of the age of the children. Not that 14-year-olds aren't interesting, but they are old enough to be self-conscious about what they say (and therefore filter it) but not quite old enough to figure out how to state their opinions clearly. However, it's still a fascinating watch. I particularly liked how the filmmaker tied in so much of the original footage - I would have had a horrible time remembering who was who otherwise. 3 stars.
