I watched it too, an interesting documentary, though I felt the non-involvement of Quincy Jones pretty much destroyed it. It was too long too, e.g, I really don't care where Justin f***ing Beaver was when he heard Jackson had croaked. I didn't realise Jimmy Smith played on the title track, so I learnt something too. I'd still argue Bad was the weakest of his three big albums, Off The Wall being the best by far IMO.
PS if buying this music on CD hunt down the original masterings as the remastered versions are pretty much ruined.
