Bro at the start of the series Finn is a hero beloved by all, in the middle of it he's a raging sperg with no friend except Jake given the cold shoulders by most characters and by the end of it he's a background character who does nothing but mop about his traumas and apparently that's "growing up". Sure the end is an improvement compared to the middle but it's less like "character had an arc" and more "series got awful in the middle and got a bit better by the end but the characters were already too fucked and they wanted to keep their lesbian drama going".
>Also pb and Marceline were never a couple in the original series
It's heavily implied, they're always hanging out together when, again, they have ZERO chemistry and are given a backstory where they always knew eachothers or whatever. One is a sociopathic tyranical leader and the other is a carefree irresponsible trickster, they should hate eachothers.
And yes I did watch the series and it does get better in the later seasons but the ending is just unsatisfying shit centered around boring characters no one cares about. The best I can say about it is they at least didn't further ruin anything major.
