Peter Ericson’s review published on Letterboxd :
This biopic about French singer Édith Piaf is conventional but well-made, even though the non-linear storytelling interrupts the narrative flow of the film. After the first act, which is only mildly interesting, the film gradually becomes more engaging, ending on quite an emotional note that is accompanied by the most appropriate song imaginable: "Non, je ne regrette rien". Unsurprisingly, the great soundtrack includes several well-known Piaf songs. Marion Cotillard’s deservedly Academy Award–winning lead performance is splendid, impressive, and thoroughly convincing, as is her old-age makeup, for which the movie also won an Oscar. Directed with care and respect by Olivier Dahan, who wrote the script together with Isabelle Sobelman.
