Showing intensely personal footage of the British star who passed away at just 27 years old in 2011 from alcohol poisoning, the trailer for Amy focuses on her love for music and the media frenzy constantly surrounding her. Set to her hit, "Back to Black," it shows the extreme highs and lows of her life, including her GRAMMY-winning moments and her famously toxic relationship with ex-husband Blake Fielder-Civil.
"I fell in love with someone I would have died for," Amy says. "And that's like a real drug isn't it?"
"I'm not a girl trying to be a star," she also muses. "I'm just a girl that sings."
The highly anticipated documentary debuted at the Cannes Film Festival on Sunday, receiving overwhelmingly positive reviews.
"Whether he [director Asif Kapadia] has or hasn't captured the true essence of the singer may require further debate, but what's beyond question is that Amy is an extraordinary, powerful work," Indiewire writes.
Meanwhile, the Guardian calls the documentary "a tragic masterpiece." "It is an overwhelming story, and despite everyone knowing the ending, it is as gripping as a thriller: Kapadia has fashioned and shaped it with masterly flair."
But the film is of course, not without controversy. Reg Traviss, Amy's partner at the time of her death, recently slammed the doc in an essay for the Telegraph.
"Amy was a real person, and what the documentary makers have done -- like so many others before them -- is effectively attack her," he writes. "They claimed to have made a serious, unbiased documentary that presents an honest depiction of Amy. Instead, they have taken her name and exploited her talent for their own ends, without taking the responsibility of reflecting the true person that she was."
Amy's father Mitch, who is portrayed in the doc in an unflattering light, has also distanced himself from the film, though the family initially gave their blessing.
"They feel that the film is a missed opportunity to celebrate her life and talent and that it is both misleading and contains some basic untruths," the Winehouse family said in a statement last month via the Guardian. "There are specific allegations made against family and management that are unfounded and unbalanced."
