This is a story I'm already sympathetic to, and playing it to the end did not somehow make my sympathy run deeper... It just made me sad, something I feel often enough regarding the situation. Without spoiling, I don't think anyone already sympathetic to the fisherman and his plight have much insight to gain here, and I'm not sure anything except direct interpersonal experiences can change the mind of someone on the other side. People are heavily polarized today, and the hearts of many are hardened beyond repair.
It's nonetheless well made. I love the music and art and the writing is quite good, even if the other man's rhetoric is a bit too on the nose at times.
