_This review pasted to the main series page from season 1. Should the series receive an(y) additional season(s), I'll update this one if and when I watch the new episodes._ ---- Average episode rating for season one: 6.76923077 The writing is fairly good, though (at least on Crunchyroll with subtitles) the on-screen information is often presented so quickly that it's impossible to read without pausing and/or without missing dialogue/action. Presumably this effect is less of an issue for the Japanese version, though I actually didn't see any Japanese text on screen most of the time. Either Crunchyroll took it upon themselves to place so much information on screen, or they were sent source video without the Japanese text layered on so the frame wouldn't look awful with English text placed on top of existing Japanese info-dumps. Most of my issues with the series are technical: simple animations, lots of repetition between episodes, and heavy reuse of animation segments even within the same episode. The germs' voices tended to be pretty same-y, too, with pretty much the same audio effect layer used for all of them (and not much variation in their lines, either). If the show had gone on to a second cour it would have been a bit much. Aside from a special episode coming out over the upcoming holidays, I see no hint of a second season yet. If one does eventually happen, I'm not sure I would take the time to watch it. The formula has been pretty played out already just in the existing thirteen episodes, and the show would need an infusion of new characters and situations to make another season interesting.
