My biggest beef with Amy Winehouse was that I never thought she was able to really translate what I was hearing on record to the live setting. When I would see her live performances on awards shows or whatever, she rushed through things, or sounded off. However, the documentary goes a long way in showing that, by the time I was seeing her live on tv, she was already in pretty bad shape. I never got to see her earlier performances where her true talent can clearly be seen/heard. That was one of the cool things about the film. It is tough then watching her slide, and seeing some of those rough performances towards the end.
