I fell in love with Lee Bong Geun's voice when watching Six Flying Dragons (which I recommend, BTW), and started researching him. When I found out that he was cast in a movie about a travelling singer, I HAD TO watch it!
How huge my disappointment was when this fascinating, unique traditional singing was covered up with generic "film music" of the type you can hear in cheap productions from around the world. Why would you do that? If I watch a movie about traditional music, I want to hear traditional music, not some stock musac.
The travelling singer is performing in front of the crowds? You can barely hear his voice from beneath a western style orchestra playing a romantic tune. A girl is about to sing a song for a granny? No way, you cannot listen to that song a'cappella, they need to play some cringy strings as an accompaniment.
You hate traditional music so you make a movie about traditional music? That's just plain stupid. Playing background music while the character is singing is in itself quite weird, if you ask me. In case of a movie that was supposed to showcase that very singing, it's absurd.
I was let down and irritated. As I wanted to watch this movie because of music, I dropped it in the middle.
