The initial idea for this series is very good, and the designs for the microbes are intoxicatingly cute (and still litter Japan).
However, the story for this series is dismal, the pacing is wrong and the episodes are disconnected thin excuses for narratives. The story goes nowhere and is forced to rely on it's characters, all of which are shit bar the microbes, which get nowhere near enough screen time.
I'm biased; I think slice-of-life is a waste of my time, but to be honest I wasn't expecting some run-of-the-mill coming-of-age life-decision-making cutsie univeristy trash when I read the synopsis.
Really dissapointing use of a great idea.
I liked the series, and still do, just because of the premise. But I hate it for dragging itself out for 11 goddam episodes. A 1- or 2-episode OAV would have been fine, and wouldn't have had to make up stupid plot element to fill time.
I can't but feel bad about the harshness of this review because the animation is good, the microbes are awesome as I said, and the OP and ED are wicked. However... what a shame about the rest.
