I'm just worried about the director. The Series Composition is being done by Shimada Michiru who made Romeo no Aoi Sora(excellent anime, highly recommended) and the others on the staff are good enough. But the director, Yamakawa Yoshiki, only did 1 notable work: Kill me Baby.
About J.C Staff. I still stand with my opinion, but only regarding KEY works. I don't think J.C Staff is capable of doing
better, but, at the same time, they might as well just do a great job if the director manages it.
I'm hardly a fanboy of Kyo-ni though. The only animes I absolutely loved from them were they adaptations of Kannon, Clannad and even Air.
EDIT: Ano Natsu rules[2].
