I'm a big of "Adventure Time" but I'm not very impressed by this. In my opinion "Who would Win", without being necessarily bad, was pretty forgettable, especially in comparison with much better chapters of the fourth season, particularly the emotional "I Remember You" and the thrilling "The Lich".
In some ways, it feels pretty much like a "filler" episode without very much relevance in the entire series. The plot was very simplistic like in some of the chapters from the first and second season (Before the apparition of the Lich) but without the same charm. Now, "Who Would Win" wasn't terrible (Unlike "Regular Show",
"Adventure Time" seems to have a much more consistent level of quality in almost all the chapters) but it wasn't very good either, in my opinion.
