Why did Tari Tari only get one cour when Hanasaku Iroha got 2? This is totally unfair.
Anyway, typical P.A.Works, starting strong and ending weak. The start of this show showcased a lot of promise, and eventually it lost focus and didn't know where it was going. When they finished their concert during episode 2 or 3, I felt that there was potential for this anime to be the best anime of this season. Well, so much for that. Aside from Wakana's arc, I also felt that most of the drama is pretty forgettable, and I certainly wasn't very moved by most of them. Even many parts of Wakana's arc I would just brush off as useless melodrama, and I really hate melodrama.
Reckoner is right in calling this show a "coming of age" series. It is centered on five members of a choir club, each with their own tribulations of 'growing up' as they strive to make the best out of their last year of high school, rectify some mistakes made in the past and accomplish their goals. The concept is good, but the plot is forgettable. Also, I think this show would have benefitted from giving the male characters some more character development. Maybe 2 cour would have fixed that. Who knows?
Overall, it's a 6/10. The ending was good and tied everything up well. In general I still somewhat liked watching this series, and it had such a strong start too.
