|It's about a Choir Club! (and sometimes badminton)|
There are plenty of works out there that suffer from the problem in that "they Get Better". We've likely all had this problem bite us at some point; Either we drop a show after the first few episodes, only to return years later and realize what we've been missing, or maybe we introduce friends to the work, only for them to drop it before they could know about that thing that makes the work truly awesome. Tari Tari doesn't have this problem (indeed, I found the quality of the series to be quite consistent from start to finish), but rather the related problem of sounding uninteresting at first.
