Almost from the opening frame, it’s clear that Amy is the first real, empathetic attempt at understanding her life, but by the time the credits roll, you will feel angrier about – and more complicit in – her death than you ever thought possible. Much of the film is comprised of candid camera-phone footage shot by the singer’s close friends and family, and it provides a new lens through which we can begin to understand a brilliant, complex artist who until now has been shallowly defined by her appearances in the tabloid press. It’s impossible to walk away from Amy, director Asif Kapadia’s controversial documentary about the life and death of Amy Winehouse, and not feel the urge to apportion blame.
