Agree, but like I said, that documentary serves more of an entry point to the endless hole that is AKB.
The message is really simple though, in AKB Akimoto created a group that unlike ones before who are able to communicate to the fans and allows fans to see them grow from nothing into star.
What got me into this group was 4 year ago in a late night drama "Strange Cases of Shiori and Shimako" (I think), in that drama, as the #2 role, Maeda Atsuko out shine the main role. Before then, I did know of AKB, but my image of them was a poor-men's version of Morning Musume, which I had no interest.
Since then I start to watch more drama and varieties with AKB members in them they they all had some sort of demeanor that other many teen celebraty lacks which got me start to follow them and try out their music. Then as more I learned about the history ad how their songs ties into that history and what the members are like it was too late. This is the first time in my life I've like an artist enough that not only did I bought the CDs, I even bought concert DVDs and documentaries.
Anyway, Akimoto rarely appears on TV. He's busy enough as is as one of the most powerful man in Japanese entertainment even without AKB, even AKB members themselves hardly sees him and only older members get to communicate with him on consistent basis. But as that documentary mentioned, almost every song had a message Akimoto wanted the fans to know and is a reflection to the members/group's state of mind at time. That is even more apparent in their stage songs and sub units songs.
Besides, their music had a lot of variety in them and once you add stage songs into that list, it almost impossible to to find a song you won't enjoy.
The AKB Thread has some links posted on their stage music or older lessor known singles.
BTW, can you read or Chinese or watching Japanese raw?
If you are still interested, they have 2 official documentary out, "DOCUMENTARY of AKB48 to be continued" and "DOCUMENTARY of AKB48 Show must go on" these documentary covers the year 2010 and 2011 the two years their popularity explodes and gives you inside on how the older member that and now left views these situation.
When I watched they, I was surprised by their maturity, you can also watch the speeches of their yearly election, it also shows a lot about who they are individually.

Show Must Go On:

I recommend "To be Continued" more than "Show Must Go On", while deserving so and understandable, there are just a bit too much emphasis on the aftermath of Japan Earthquake last year.
