I just watched this movie, it was incredible. Marion Cotillard looked nothing like the character she played, which impressed me further as she was able to dive into it and bring life back to the old singer from her teens to her death. Although the story was non-linear, it still kept a decent storyline along. Even though the movie was primarily in french, I could personally tolerate the subtitles and get into it just as well as if it was in English.

I highly suggest watching this movie.
