This story is about a comet which is due to hit the earth in a matter of hours and how a song from 1975 called "Fish Story" will save the world in 2012. How? Thats part of the fun in watching the film. The film has some comedic moments in that you have references to superhero(ine) series from Japan, as well as other cultural mores. You see what appears to be a series of unconnected events somehow gel. The song itself is a proto punk song, recorded before the Sex Pistols, and its actually a good song. The acting goes all over the map, as there are flashbacks with disparate characters, but it is pretty much all good. Whatever the ending, you have to stay for it to see how things tie together. The world could come to an end (Japan would be pretty much submerged) if the comet hit, so just watch. It has a kind of new wavish sensibility, especially the scenes with the band who recorded "Fish Story". Not perfect, it drags slightly at times, but its worthwhile. I recommend it.
