Personally I think she's a cute
Because she's an immortal dictator who rules over the Candy Kingdom with an iron fist and an Orwellian level of privacy invasions. She's literally got every quality of a D&D campaign's main antagonist besides a capable army and an aggressively imperialist foreign policy.
Until the third season, she was my favorite character. Now I only have those memories...
Never really liked PB. She got sort of fun for a while with all the quirky mad science girl stuff which was at least funny at times.
Now she's some lonely loser damsel in distress for creepy internet dykes to come swoop in and save with their creepy fanfics/ships.
Stopped watching AT for awhile but I remember one of the positive changes in the shows downward spiral was her moral ambiguity. It made her character more interesting and gave her a lot of great jokes and lines that she wouldn't normally say back in the shows heyday.
Because, like all sperglords, /co/ can't handle being friend-zoned. Not even vicariously.
Implied, but it's unlikely they'll ever fully confirm or deny it.
>Trying to make Marcey look bad because she has flaws.
Her Bisexual/Lesbian sexuality was nice when it was a background thing, not a full plot point. It's annoying as fuck, and a disgrace to real Lesbians who have to sit through this crap when all they want is the "Adventure" in Adventure Time, not "Bubbline Fuck Time"
