TWO WORDS: WATCH IT
I will write a full review on it i'm just realllyyy tired and I has stuffz to do so i'll write it up tomorow when im free, but on all honesty one of my favorite anime of all time. If you love romance/drama/comedy then Clannad is a must see! and after Clannad comes Clannad: After Story, which is even better! it even makes it into magica 10 land.
Should you watch the Clannad series?
A- Why Not!? Seriously...
