She was great in this movie. She managed to turn a movie that might have been a bit slow and predictable into a movie that was enjoyable to watch. The character under Julianne's acting skill really drew me into the movie and John Turturro was a great complement. The music and dance scenes added an air of optimism and made you root for her to have a happy ending. Julianne ably showed how life changes are not always controllable but music can be a great escape.
Overall, anything she acts in is usually a winner.
