OKish documentary about NMB48 and associated 48-idol groups. This was commissioned by the company behind the empire but with the intent to do things a bit differently (this isn't the first documentary about them which they produced). The framing follows an outsider's perspective of the idol industry which reflects the the director's standpoint. If you're new to the topic it certainly fulfills it's duty but otherwise you'll be missing an element here. I would have loved to see a bit more of the drama elements behind the scenes (caused by the hierarchy) but I can see that this probably wasn't the context for it. Note that despite the production background it still highlights many of the shady areas of the industry (only one scene needed to be left out).
