I just finished listening to the audiobook of Manhood for Amateurs by Michael Chabon (also read by Chabon, who did a great job, I might add). The book covers a lot of territory, considers adulthood, childhood, his fatherhood, how he relates to his kids, how he related to his parents... He's got 10-12 years on me, and so is a product of the 1970's, a period I see in my mind's eye with a weird aura of gold and washed out color thanks to the film stock and production values in vogue at the time.
He talks a bit about how we mourns the content his kids have to consume, the formulaic closed-endedness of a cute but structurally dead-ended bit of Dreamworks entertainment. He admits that between what the 90's called helicopter parenting, and this closed-off world of entertainment, he doesn't think his own kids really understand what it means to have an "adventure". After all, if you're not letting your kids go beyond the end of the driveway, or out into the yard without supervision, how can you ever experience the unknown? And its reflected in a lot of juvenile lit and entertainment.
He also discusses how he relates to his kids through media, how he's raising them on a steady geek-diet of Marvel comics, Dr. Who and other bits... things that he enjoyed alone once, but that is creating bonds within his own family.
I've got no kids. I don't often think much about passing on my passions to anyone else (Scout, simply, does not care about Superman. She's sort of an X-Men fan, and I assume she'll grow out of that).
