Is SuperS Under-Rated?

That's understandable. Personally I think they gave Tiger's Eye too much screen time compared to Hawk's Eye. Since the latter targeted more mature women, it would have been nice to see more older women as original characters.

I . I think the first season actually has a lot more filler-in episodes

than SuperS and most of the 90s anime is completely different from the manga, so I don't it's fair to hold SuperS to a higher stander of manga accuracy when fans don't do it for the rest of the anime.

The Doom Tree and Nehelenia arcs are some of the best arcs of the 90s anime and they aren't even in the manga at all. I enjoy Sailor Moon for it's characters and stories and not because one season is darker than the other and I personally enjoy the 90s anime for a lot of the comedy that I feel like the manga lacks. I would also argue SuperS is darker than fans give it credit for. The Amazon Trio basically try to murder any of their victims that don't have the Dream mirror in them. Nehelenia turned all her servants into horrifying monsters so she could have eternal youth. The MOTDs in SuperS are pretty twisted and creepy in general and the scene where you find out Zirconia is Nehelenia's reflection is very creepy.

The Quartet definitely has more personality and development than some of the later members of the Witches 5 like Tellu and Viluy.

for God Sake, Sailor Moon cannot even transform or launch an attack without her; with the exception of Moon Tiara Action

One of my favorite SuperS episodes is when JunJun gets frustrated seeing Chibiusa's friend failing at the box vaulting so she tries to use her magic to help him jump over it even though he was supposed to be her target and I think that was the first signs she wasn't all that bad but she was still in denial about it. Even though it was a pretty simple plot for the episode, I think it makes JunJun stand out more over other villains that only go through a reform and show any kindness after their shown what kindness is by Sailor Moon. Of course Sailor Moon is ultimately the one who shows her the way, but I thought it made her more complex because even when she was a villain, JunJun still had different sides to her.
