I have to say, my only complaint is that this documentary is not long enough. I could go on watching stuff from that pile of tapes they showed at the beginning for days.
I think the choice of clips is more about relevance and time constraints than showing what the girls did all these years day by day. But if you want to see more, there are clips played during their anniversary ustreams found on their ustream channel that aren't featured in the documentary. And there are also clips available only for AE club members from what I'm told.
