On Sunday, my husband and I saw “Amy,” a new documentary about the late Amy Winehouse. Since Amy died in 2011, there have been several documentaries and shows about her, but this one was different in that it was told in her own words through unseen videos of Amy throughout her life. Award-winning director Asif Kapadia, known primarily for his 2010 documentary “Senna,” directed the film, and carefully crafted a stirring and sad portrait of Amy’s life using home videos and TV clips of Amy through time, along with interviews with her closest friends and unheard tracks.
