Yuru Yuri 8
Pretty good episode, but it was lessened quite a bit by an overabundance of the terrible Chinatsu. On top of that, any amount of focus on her pairing with best girl, as was shown in the last segment, is entirely mediocre. All in all, this episode needed more Kyoko x Yui, as does the entire show. The tsun duet between Himawari and Sakurako was great though, as were all the scenes that involved Kyoko being awesome.
However the festival arc had a decent amount of character development and interaction and it managed to do all that without being as dull as growing mushrooms. That is major strike against the episode and the series as a whole.
KyoAni studios are infected by 'boring' and I don't know how they can be cured.
Even though I thoroughly enjoy Hyouka and consider it one of KyoAni's best shows, I can definitely understand why some find it boring. The only show by KyoAni that I consider to be rather boring is Nichijou, and a few particular parts of Haruhi.
Although it certainly remains to be seen, Chuunibyou looks like it has the potential to be a considerable departure from their "duller" works.
I suppose, as jman pointed out, that it mostly comes down to what they've chosen to adapt. They certainly have the talent and ability to create more appealing/entertaining shows, judging by their consistently unique and imaginative commercials. I think they're one of the top studios though, so I've never had a problem with their style.
