I must confess that I have seen this movie in the last 3 days at least 5 times.
Authentic, simple yet classy, relatable, believable and even though it is predictable you feel radiant joy that nothing was changed when you are done watching.
You might not get to watch the movie more than once but I can bet you would watch many times over and over again beautiful scenes where Christopher played his songs.
Absolutely fantastic feel good movie.
