I like Clannad too. =) I've seen all 23 episodes and I can't wait for the After Story to be released. ^_^
Apperently there's also a movie, but I'm not sure if I'm going to watch it or not.
And don't worry about being new to the show, since the show is quite new itself. It startet somwhere in October/ November last year I think, but I'm not quite sure.
My favourite characters are Tomoya, Kotomi and Fuuko.
