This film is totally over the top. First off, it has been greatly imitated. Second, Zubin expresses his deep "passion" for the music, while the members of the orchestra play it dead pan. There is one great scene where a young violinist nearly rolls his eyes. The haircuts and clothes are absolutely terrific. What is great, is some of the players really try to play up their excitement, and the other members of the orchestra play it as it is.
The ending is really iconic. Zubin is practically dancing to the music near the end, and for the very end, he spins around, and the music stops, the picture goes black! This is the orchestral style you wanted to see when you were ten. Especially the cut scenes between Zubin, the drum, the tuba, and the light behind him.
