I noticed on reviewer completely hated the film and talked about racism in America. Well, I could understand some of their feelings though to only dismiss the film for racism would also ignore the nice performance by its star, Mel Bryant (who I assume also played the trumpet in the film...and amazingly well).
The film is set during WWII and a young man (Bryant) is trying to guy a bugle...though he doesn't have enough money. So, he sets out begging folks to let him shine their shoes so he can earn the needed $4 before the business closes. He isn't very successful until he gets a chance to play trumpet with a band...and he is amazing. So why does he need a bugle and why now?
Okay...the film does have some offensive content. Calling this man 'boy' throughout the film (as well as in the title) is not right, nor is some of the patronizing style of the film. But, it's a product of its times...and the conclusion especially so. Worth seeing...just understand that in 2017 it is bound to offend, though the film is well made and the trumpet solo is amazing.
