I watched it about 2 months ago. It had some interesting things that I've never seen before like footage of his swiss house.
I doubt that anybody takes Angie seriously - she even shot her credibilty in the foot within her own interview.
I bet most people don't know about Bowie's art. It won't change value, but at least they did feature his work in the show. They were nice about the wallpaper.
I was a bit bothers by them showing Bowie's NYC swank apartment. Bugged since they virtually gave away the address which I wonder is even completely legal.
