Clannad is the story of two kids who meet in high school, get closer as they work through problems together, and eventually get married and have a family. Boring, every-day stuff? Emphatically NO!
The main characters are Tomoya (a so-called delinquent with family issues whose worst offenses are skipping class and playing pranks) and Nagisa (a frail girl whose wacky parents dote on her). Throughout the first season, they meet a host of off-kilter characters and help them out. A barrel of laughs comes along with these characters' bittersweet stories. All the while, an alternate fantasy world is weaved into the story bit by bit.
The second season is Clannad After story, which focuses on life after high school (and Nagisa and Tomoya's romantic relationship/soon-to-be new family life). It starts off with the same tone as the first season. In the second half, it completely changes gears. HAVE A TISSUE BOX NEARBY!!
I personally have a love-hate relationship with this series. It's so well-done, you have to love it; but it will make you bawl like a baby. Clannad is definitely in my top 5 anime.
