This is just something that I've been thinking about off and on for quite some time. In most shounen or seinen manga series, the characters are treated as individuals, having little or nothing to do with their parents. Mitsuru Adachi's series are pretty much the only exception to this that I can recall offhand. Parents in shoujo and josei series usually have more influence over the story, but much of their role revolves around either being a source of conflict (repressive/forbidding parents), comedy (Haruhi's father in Ouran High comes to mind), or the cutesy let's-take-care-of-a-baby type (Aishiteruze Baby, Daa Daa Daa, etc.).
So, my question is: What do you think of the way that parenthood is portrayed in manga/anime? Is it accurate or realistic? Are there any examples of manga/anime which you think portrays the nature of parenthood really well or explores the parent-child relationship deeply?
