While Cartoon Network’s animated series Adventure Time is a fun show about adventures in a fantasy world, it’s always had a deeper, sadder side. Whether it’s Marceline singing to the Ice King about how he can’t remember who she is or Finn hugging his mother for the first time, creator Pendleton Ward never held back from the emotional gut-punches. It’s fitting, then, that the first episode of HBO Max’s Adventure Time spin-off Distant Lands captures that same melancholy feeling on an otherwise fun romp through space.
