Clannad

On your way to school, you'll have a romantic meeting with a sweet girl. You'll forget all about the time, and that's why you're going to be late...

This anime is very cathartic and one of my absolute favorites.

I do not necessarily think that Clannad presents noble intentions. There are anime that are made better by the intentions of the creators, and theoretically I think Clannad could benefit from some changes in this regard. Nonetheless, it still manages to have a captivating atmosphere, emotional drama, and all-around beautiful production.
