The ending was sad but I still loved it and love the show entirely!
Everything’s perfectly normal in the Land of Ooo. Finn and Jake are investigating a haunting, BMO and Ice King have become door-to-door salesmen, and Flame Princess is getting hyped up to battle the Son of Rap Bear. Oh, and Ooo just happens to be on the brink of an all-out, catastrophic WAR! Yep, perfectly normal.
