Let me state right from the start that the two best anime series this season are continuations of existing series.
Showa Genroku Rakugo Shinju: Descending Stories (Crunchyroll) should wrap up the story that I praised here and here. This is a sophisticated drama, well worth your time. (If you haven’t seen the first half, be sure to watch it first.)
This will probably be the final cour of March Comes In Like A Lion (Crunchyroll.) This is a smaller-scale story without the grand historical sweep of Showa but it’s an effective personal drama that is sometimes chilling but often heartwarming. See my post here.
