I don't know the original story but I found this movie enjoyable and heartwarming. One critic here may be right that a real conductor should have improved the actors performance but I could relate to the father-son-conflict as well as to the relationship between a conductor and his love interest in his first violin. Well played, well shot, a small European movie that obviously hasn't made it's way into our movies, but thanks to streaming came to my attention.
Hoping the movie finds it's audience here. There should be place for small movies between all these Deadpool, Wolverines and Jokers and other blockbusters.
