I've been enjoying Clannad After Story an awful lot. I wouldn't have imagined that an animation team would take the after-the-resolution of a dating sim & make a family drama of it. The whole show is basically post-climax, except they're not treating it that way. The heroine is sickly, so she ends up repeating her senior year - again! She's actually a year older than the protagonist, because they met on her second go round at trying to graduate. He was a goof-off during high school - a self-described "delinquent" - so he ends up getting work where he can, and ends up becoming an apprentice electrician with a small local contractor. The show spends two-three episodes with the protagonist as he works his way into the honest-to-god Japanese blue-collar lifestyle.
The above was written before I watched the second half of the second season. Wow, what a series of gut-punches. The entire series, both seasons, are in retrospect *not* dating-sim stuff, but rather a rather sharp-edged family drama with magical realist overtones that just uses the *furniture* of moe dating sims. I can't believe I once dismissed this series as "retard moe". Sorry, Kyoto.
I still think K-On! is stupid, though.
