…and we’re really into tremendously long series with good characterization.

Found one. Hikaru No Go. About a boy prodigy in an obsessive and cerebral adult game (Go) that you could call Asian chess—it’s a really good story with actual re-watch capability. Available in Japanese on streaming Netflix: 75 half-hour episodes. No, you don’t have to know Go to enjoy the story, though you will learn some along the way. Honestly, as Jane said, it’s a good thing we didn’t find out about this game when we were kids. It would be very easy to get sucked in…and in this country, there aren’t that many people to play it with!
