Everything was out of order. Different periods of Maryla's life were mixed tohether and the movie often jumped around years loosing continuity of story. It was too confusing.
Maryla herself was and still is an amazing singer and a star (obviously). Frankly, I don't regret watching the documentary for the sole reason that it was about her. If it was about any other person though... I probably wouldn't finish it.
I see what the directors were trying to show and tell, but I also see that they lacked understanding of how a story such as this one should be told. If only the events presented in the film were organised, it would've been a really good watch. Instead... I can only reccomend it strictly for Maryla's fans.
