The setting is totally different, the characters are mostly new, to be sure, but the sometimes chaotic flow to the narrative and the band of non-kidnappers remains. That's what made the original series and spin-off so unique. And yet, Adventure Time: Distant Lands - BMO is also more streamlined, a little bit smaller, as it does not have the advantage of exploring its mythology over dozens of episodes like its predecessor.
The little saga includes a reasonable amount of knowledge and characters at that time of execution. We met the young teenage scientist rabbit Y4 who makes observations on a failed space station called 'The Drift'.
The problem is when you feel a little rushed when it comes to stories and development of relatively new characters. There is simply no time for fans to develop an emotional and deep attachment to these characters when their lives are overturned, we feel something strongly in one way or another. Fortunately, BMO acts as an emotional anchor in this case. If this freelancer had simply started following these new characters, he would have felt derived, a pale imitation of what made the original Adventure Time so good. For both the characters in this special and the viewers at home, BMO is here to save your day.
