yeah its not a great documentary. the fact they are the ones interviewing everyone makes it a bit like their show, and thats not really what you want for a film like this.
youre right, they did touch on the schisms (stretch starting a label that put out more thugged out stuff, and bobbitos label specialising in more 'undie' stuff) that rose up in the late 90s, and how in a sense, it helped drive them apart, but it seemed like a moment to actually shed a bit more light on their relationship, and their breakup, one they didnt really investigate. someone else holding the reigns could have done a better job.
it didnt really give you the context of what else was happening in rap radio at the time, or in the city even, only occasionally touching on clubs being dangerous, etc. there were other rap shows at the time, and mixtapes, so the doc somehow underplays what they did differently, and overplays it at the same time as it ignores other guys on radio playing hip hop both before and at the same time as S&B. also, for such an 'underground' show, even allowing for the fact that nas, jay-z and everyone else werent really popstars at the time they were on the show, i think they should have featured more underground artists too, the people who popped up, killed it, but never made it that big.
it made me think of what a film about, say NWA would be like, if ice cube and dre were interviewing everyone else, involved with the group. most of the interviews were like what youd get on a typical rap show. you dont really get that deep into it.
