Yeah, I like having it all...lol. Good characters (Moon), bad characters (Death Busters) and gray characters (Uranus and Neptune.)
I like light and dark motives in a story, like old fairy tales...but even some of those were very gray and ambiguous.
PGSM also did it well, leaving plenty of gray areas. Beryl is a villain...but is she purely evil or is she doing what she has to do in order to thwart both Metalia and Serenity?
Meanwhile, Serenity might not be maliciously evil, but she's still major antagonist material. Yes, she has motives, but those motives are pretty much screw everyone besides me and Endymion, lol.
