This anime is the peak of the melodrama craze that was going on at this time this anime was aired. And of course, it was a HUGE success.
But it's garbage. The fact of the matter is, the contents of this show are so minimal, and any plot really only happens at the very beginning, and the very end. There IS a deficit in too slow paced episodes, especially when its badly made, and show no purpose. This anime could have been made into a 90 minute movie, and I'm sure it would have turned out the same exact way. And of course, the entire premise of this show that turns this into an actual "drama" is the (SPOILER) fact that the girl is going to die. OK. So lack of ability to write a romantic story about a guy and a girl who like music makes the author, instead, crutch himself with a plot device that anyone can make into a sad sob story.
