Don't have a straight answer, but what drives me from watching this was 1: The main plot, 2: Starco, knowing that they'll be endgame, and 3: How unexpected this shit can be.
A bonus is just Star. I mean, you have to understand a deconstruction of certain archetypes like Magical Girls or princesses. If you keep it straight, then that character will be a dime-a-dozen if you tend to watch more. Deconstruction goes far deeper, giving better character development, making them feel more unique, apart from the very outside which you people consider otherwise.
So in this case, Star went from a care-free interdimensional bug princess to a jealous insect, then soldiered on as she "died," cheated death, cheated her demon boyfriend, went through an identity crisis, gave up the crown, and now the end is uncertain, but she has matured throughout the entire run. >Worst part?
Only a few episodes disappoint me, especially Club Snubbed. That, and a certain horse head who has an ego equal to Johnny Cage. Difference being is that Cage is more likable with his snark, while Ponyhead's a bitch.
Also to those who said that Jackie's gay now.... Grow up, please. She's just a side character.
