Oh, just wow. I must say this was done pretty nicely. My early expectations for the ED was rather uncertain, since it was nicely named “Dango Daikazoku”, but they’ve done a very nice job on it. At the end of it, I even had some tears welling up in my eyes.
A discourse by two random occupants of #animeblogger nicely puts it in context:
<meganeshounen> How can a song about dangos be so touching? ^_^;
<totali> how can a song about dangos NOT be so touching?
Also, managed to watch a higher-res version of the CLANNAD OP, and I must say…. seems to be tons of spoilers thrown in there by KyoAni.
