RIP KyoAni.
They're very hit or miss, but they usually have some good stuff. I found Fumoffu, Clannad, K-On, Hyouka, Amaburi, Euphonium, and Violet very enjoyable shows. Stuff like Lucky Star, Haruhi, FMP:TSR, Maid Dragon and Kanon were also enjoyable but not to the same degree. The rest including Air, Nichijou, Chuu2, Tamako, Kyoukai, Free, etc. I can say were not my cup of tea, but I can understand why people like them.
The movies are also very good. I don't think I've disliked a single movie from them and it even made me appreciate some of their TV series I didn't particularly love. Most anons can see merit in Disappearance even if they didn't love Haruhi for example.
