I liked this less than Shonen merikensakku. Honestly, I was so uninterested, the big twisty come-together at the end was lost on me. I kind of tuned out way at the beginning when the characters seemed more like plot revealers than real people. The guy with the cane killed the movie for me. Oh! hey, but Noriko Eguchi is awesome.
"Fish Story" centres around a rock band from 1975 who decide to break up having had no success, they record one last song before the band splits up. Decades later that song will have a profound effect on peoples lives, eventually becoming the saviour of the world.
