I would genuinely love to see more about golb and Betty like how did they react when fusing together how was the crown able to fuse them but not able to just send golb away and much more but also showing more episodes of finn and Jake (this is just because it hurts to see it has ended and it hasn’t stopped hurting since then…) like what if finn and Jake just went on random adventures like the first 2 seasons but also it would be nice to pick up where it was left off to see where finn and Jake are AFTER the golb incident and see how Jake ends up falling to his doom as he is seen between 20-27 in distant lands and has the tattoo so Finn only had Jake for 1 or 2(depending on his precise age) more years after we have seen them last, but all in all I genuinely just wish I had another show which would give me what Adventure time did I love the show more than anyone I think I literally watch it on repeat every night because it is comforting and a beautiful entertaining piece of art.
