I am writing this review August 29, 2023. This anime was released in 2003. In that time there has only been 283 reviews with 2 written ones and a total aggregate rating of 7 out of 10. That's a high score for so few willing to watch this single season series. I did watch the whole thing on Prime because of this rating. Unfortunately. They rated the program at 18+.
Each episode is a separate story that is loosely tied to each other by virtue of the fact that the four main characters appeared in each one. One of these characters was completely redundant contributing nothing to any part of the story. Had he disappeared completely, the story wouldn't have changed at all. None of these characters is fully developed and the viewer will have no emotional tie to any of them. You will not hate them. Neither will you like them. They are essentially unappealing and uninteresting.
Technically, the anime is falls into the poor half of the animation spectrum during the time it was made, not being well done. In today's terms, it's not done well at all. Nostalgia won't save it.
The music falls into the elevator spectrum of jazz, not matching any of the story actions or emotional events. There was nothing to be excited about at all here.
The writing quality was poor and you could have driven a truck through the plot holes that occurred every few minutes during viewing. The story held some adult themes (hence the rating of 18+). However, it was so poorly done that it could only have appealed to prepubescent eleven year olds. The favourable ratings probably originate for this reason, as something like watching "forbidden fruit" for a very small demographic. There was little, if any adult sophistication demonstrated. For anyone else, watching would be painful, if not downright boring. That is why there are so few reviews. Hardly anyone got through the first episode.
To be fair, if you have a great deal of patience and are bored out of you mind with a lack of any other pastimes available, you could watch it to kill some time. Just don't expect much from the series. It is very lacklustre, bland being the best description and doesn't deserve a high aggregate score.
