Such an anime shouldn't typically work, but in this case it's fine cause Kanye is superior and knows that he's superior. Such concentrated incompetence as what the fairies demonstrate I haven't seen in a while (especially Gatou's favourite fairy). In fact, Cirno does look like a genius when compared to them. So it's fun to see them suffer. Except this also means I didn't care at all for the subplot with the princess fairy. But oh well, at least we don't spend too much time on her.
That being said, if they had aired the PV episode first, it'd've improved the overall experience significantly. Unfortunately, this was not the same KyoAni that made Haruhi.
