After the first episode I was hooked. This isn't your traditional anime. It is more like poetry. From the first episode I pretty much knew that I wouldn't regret spending my time with this show. Little did I know, it was much more then that.
As the show progressed I realized that it wasn't the usual teenage drama, it delved into some really emotional themes. Clannad pulls at your heart at every chance it gets, and when you're down and you think you can't take any more it kicks you again.
The animation style was beautiful as well, it gave a euphoric feel to the entire show. The character design was rather bland but being based off a graphic novel the character design was spot on.
Clannad has had a weird emotional impact, one that I can't really explain. All that I can say is that it was beautiful, emotional experience. It was poetry. It wasn't simply another good anime, it was in a league of its own.
I highly recommend that you watch Clannad and Clannd After Story but be prepared to feel emotions you have never felt with any other anime or TV series before.
