Not blob, no.
Characters have fairly sharp features except for Chitanda.
Moeblob is less about being an amorphous splotch of paint, and more about being an amorphous splotch of tropes and appeals.
You have to give credit to a studio that knows where its artistic strengths are, and knows what it wants to do. I think the people at KyoAni genuinely like their niche and are passionate about its execution, and it shows in their works.
It doesn't hurt that KyoAni pays three or four times the industry average.
From a social perspective, I love what they do. But in terms of output, there just isn't that starving-artist hunger, that invention mothered by necessity, that "one shot don't fuck it up" almost performance art immediacy.
