So you are making anime. Story is great, characters are colorful and lovable, Ast style and music is amazing and fit soty perfrctly. After 9 amazing eposodes story reaches culmination point. Audience is very involved and is waiting inpatiently for fitting ending. What do you do?
YOU MAKE LAST TWO EPISODES MEDIOCRE.
Why? Because anime, that's why! Manga did it better, again. It could be 9/10 if two last episodes were as good as rest of the plot. But conclusion was just so underwhelming it dragged score down to mere 6/10. It's fair anime that could be great, but wasn't.
