Majutsushi Orphen... Hmmm. You can always read the description that MAL gives you but it doesn't do the anime any justice towards its story whatsoever. It has a somewhat deeper demeanor that gives the viewer a new way to view the world around them.
Considering from other anime series, this one is one of the best classic anime that is possibly unknown to most people (even though there is a PS2 game for the series that came to the US). In my opinion, it brought upon the stigma of 90's anime which mostly consisted of action, adventure oriented material. One of the main reasons that it is a good anime to watch is if you get tired of watching romantic and slow paced anime then this is a nice change of pace. Another reason is that it goes beyond just the fight scenes and into what is really important which would be why people act the way they do.
The sound and art of the anime are exactly what one would expect from the 90's. The only qualms I have is that the soundtrack was good but I wouldnt say it was spectacular by any means whatsoever. The artwork on the other hand was well done. Especially the backgrounds that were placed in each episode.
Overall, it is an anime to watch but be mindful of some of the characters. In my opinion, be open-minded since at some point there might be ones that you either enjoy or dislike. Yet this happens in almost any series but don't let this take you away from the storyline which presents itself nicely.
