If you’ve been tracking the goings-on at the Cannes Film Festival this week, you know that one of the best reviewed films of the fest so far is Amy, a documentary on the life of the late singer/songwriter Amy Winehouse. The film, which is directed by Senna filmmaker Asif Kapadia, has gotten near-universal praise. It’s currently at 100 percent on Rotten Tomatoes, with lots of other positive reviews out there that haven’t been added to the site yet (like a glowing rave from former ScreenCrush critic Jordan Hoffman at Vanity Fair).

As Hoffman describes it, the doc blends “a mix of private video footage, feeds from various public appearances, and audio interviews with family and friends” to tell Winehouse’s rise to fame from humble beginnings, followed by her rapid descent into addiction and her tragically premature death. It considers the toll her fame took on her life, and while there’s plenty of Winehouse’s music on display, Amy also weighs the value of those incredible songs she made (“Back to Black,” “Love Is a Losing Game,” and the now impossibly poignant “Rehab”) against the years she lost as a result of her success. By all accounts, it is sad, powerful stuff.

Amy opens in theaters on July 3. Not exactly traditional summer viewing, but if you need a break from the superheroes and smash-’em-ups, this could be a good one.
