This movie is the story of back-up singers and it mostly follows Darlene Love but there are other great chops like Merry Clayton (that voice on the Rolling Stones "Gimme Shelter") and Judith Hill. Let me say this up front: if you like music, you'll like this movie. If you love 60's music, you'll love this movie. My teenage son was kinda "meh" about the movie because he didn't know "He's a Rebel" by the Crystals.
I loved it. The Darlene Love story alone is worth it, especially about how she got so fed up with Phil Spector that she quit the music business altogether and started cleaning houses. Now she's in the Rock and Roll Hall of Fame.
