Straight Edge: The Documentary

Anyone else seen this? Narrated by Thurston Moore and airing on The National Geographic Channel. I can't imagine anyone here really giving a toss but if you've seen it, what do you think?
There's nothing here you wouldn't already know but I'll save my personal thoughts for later. Many of you don't know me here but as much as I am not into drugs and drinking, I do drink occasionally and sometimes smoke the pots.
