posted about here by Sparf, (and before in unsearchable archives) is Capeta. I just burned through all 52 episodes in the last 2 weeks. I love Initial-D but IMHO, this is so much more thorough. Starting from make believe on the floor with a lego car at 10 and ending where big talent with tiny budgets can go. It explores joy, debt, and commitment to yourself and others.
click on Sparf's post. Watch it from ep.1, and just enjoy the whole thing. They got it right.
