I've seen this film quite recently and enjoyed watching it.
This is the story of Enzo Ferrari and his deep down emotions and pain even he isn't aware of. That's why his alter ego appears as a reporter and helps him to face himself.
His sorrows and regrets come secondly in this movie because of the dream-like atmosphere and the music that creates a mythical world. I guess the director is really a big fan of Ferrari. It is good watching material but can't be a superb biography.
