As a kid I thought the "relationship drama" ruined the show and began the show's decline starting with the introduction of Flame Princess. I just wanted to see Finn and Jake have fun adventures, no "girl problems".
I still feel the same, but I think they at least should have committed to something since they wasted so many episodes of the show on Finn's relationship status. It's unsatisfying that none of those episodes built to anything.
It reminds me of Regular Show's ending where Mordecai ends up with some random bat chick after flip flopping between Margaret and CJ through the whole show. It feels like all that buildup was a waste of time.
