Very average entry into the "character gets transported to a fantasy world" (aka Isekai) genre of anime. The animation is competent but doesn't stand out, the story is quite run-of-the-mill, and outside of the robot character named MOS, no one is particularly memorable. There's nothing honestly wrong with it, as it doesn't feel rushed and comes off as a complete tale, but it's all very "been there, done that", even if you watch it and put yourself back into a 1990 frame of mind. Granted, there weren't a lot of these types of anime at the time, so maybe it did somewhat stand out, but right around the corner were series such as Magic Knight Rayearth and El Hazard, which absolutely blow this out of the water. This makes for an interesting history lesson for those super into the isekai genre, but that's about it.
