Prior to watching I was leaning toward one star based on the cheap cover, moronic title, and a theme done many times before, i.e. young singer with big dreams comes out of nowhere w/some obstacles along the way of course.
What turned me into a strong supporter? Great acting by Elle, Agnieszka (played the tough mom to humorous perfection), and Zlatko. Great blending of music w/changing scenes. Great camera work & editing. Good choice of songs, many by well known artists. Finally, and no way the least, Elle did the singing. I first thought it was professional voice dubbing based on range, emotive presence, pitch quality, but nope just her.
Bonus: Elle watches "The Voice".
