Being truly objective, perfect marks across the board. Not exactly what I was expecting, especially since the direction of the first episode is not the direction of the series as a whole. But this show is very high art and obviously a labor of love. Though the "magic ingredient is friendship" trope is played so often it might make some people roll their eyes so hard they hurt themselves.
Cinema-quality use of detail and color, a slightly avant-garde character style that seems a little jarring at first but grows on you, a dreamy (and tear-jerking) score, this show is a must watch for anyone who wants to relax and not worry about forced drama or a big bad that has to be dealt with. Even if you don't like school life or shoujo stories, this is still a very well done piece of work that you should seriously consider.
