Interesting. I've never heard of it, but judging from the name, it's probably just another portrayal of her downfall (because we all totally forgot about that)
It's the same thing for all musicians/celebs with a tragic life. There's so many sensationalism docs about musicians were the music itself never gets mentioned. It's the same thing with non-fans in general. When I mention to people that I'm a Amy fan, they immediately want to talk about the morbid stuff, not the music. I just keep quiet when that happens.
I like the Amy doc on the "Live in London" Bluray, which was produced by the record company.
