one of the most emotional anime i've ever watch...
but i felt a physical mismatch between yuuichi and ayu...
i prefer makoto or naiyuki but oh well that's my preference...
you don't have to watch kanon 2002 first, but i did simply to put it in order and compare... of course, 2006 is better because of the art (and i love sarcastic guys as main characters, such as ones from haruhi/clannad), but 2002 is alright.
Not Really But If U Want To Understand wat happend on 2002 ill say its good but its not nessesary. Kanon, Air And Clannad Best Animes!! Gaoo! , Auu , Uguu. =D
