I have to disagree with the other review. I'm not a fan of Claude François, I'm not a fan of the 70s, yet I loved the movie. And that's because of Jeremy Renier's amazing performance. He's extremely magnetic, doesn't show any of the French (slightly precious and fake-sounding to me) brand of acting. The film isn't perfect and the script, certainly, would've deserved some work. It's rather descriptive and chronological. Yet I enjoyed every 158 minutes of it and that's what matters. Renier is AMAZING, so is the production design by the way. I would definitely recommend it to people who don't care about Claude François. If only because he's the guy who wrote one of the most famous songs in the world, which most people would attribute to Sinatra: My Way.
