This movie has it all; nice photography, adequate directing, good acting and nice soundtrack, except from the script.
If you are not familiar either with the protagonist or with her songs, this movie doesn't concern you. In an effort to portray the main character and her life as close to reality as possible, it would have been better to make a docu-style mini series.
If you want to have the audience's interest you have to make them sympathize with the hero of the story. This film doesn't get there. Instead of approaching the story from an anthropocentric point of view, it does so from a reporting one. It gathers all the main events of the hero's life and links them uncohesively.
The end result is pleasant aesthetically but uninteresting story-wise.
