I say the good parts first. The best 3 minutes in each episode are OP and ED, both animation and music in those. If this would be short OVA where Ayu eats different kind of Taiyakis in strong wind and after that run in the snow this would be really good.
Unfortunately there is one small problem which is kind of hard to ignore, the show itself. Things don't develop fast enough and how every girl in the town seem to bump into Kyon isn't that exciting to watch after the first time. He doesn't even have any sarcastic lines, those would save a lot. I don't usually complain about lack of plot, but this time I have to, the cast here isn't enough to keep me not thinking what to do next while waiting the end of episode. Compared to rest of garbage out there for it's genre Kanon isn't too bad, but that's hardly a praise. Overall animation is nice, but I can't see myself watching 24 episodes just because of that.
