I didn't really get a sense of internal strife that would lead me to believe the author is developing the characters beyond the surface level. And I didn't feel like there was a lot of change in characters between the beginning and end of the show, and most events seemed to leave the characters nonplussed, with very little emotional response to the things going on around them.
I can totally understand you getting this feeling from the anime, but really, you have to read the manga. While it obviously doesn't have the depth of exploration of the topic that it would if its characters were adults and came at their situations as adults, I still think it's a very powerful series.
There is a distinct lack of conflict to the show, which I consider an essential component to any story. Maybe this absence of conflict is the reason I don't feel the author has a particularly strong grasp of masculinity, or what it means to stray from or towards it.
Well, but I think the fact of the matter is this: Nitorin isn't masculine. He has no idea how to be so, and that's where part of his struggle comes from. The topic of masculinity comes from Takatsuki, the main female character, and that's exactly how it makes sense. She didn't get as much of the spotlight in the anime as Nitorin did, but her story is that of not totally understanding what it means to be feminine, because all of her feelings tell her that that's not who she really is.
I'll probably try it out, but ultimately the anime has to stand on its own as an entity separate from other works.
I absolutely agree, and as much as it pains me to say so, I think the anime was a failure in that regard. But, really, I can see almost
no way it could have been done well while (a) retaining the spirit of the manga, and (b) hitting on enough points from it to satisfy fans without making it some completely different side-story. Unfortuantely, I think it was one of those "damned if you do, damned if you don't" scenarios.
I think it ended up having two successes: making Hourou Musuko fans happy to get to see
any part of the story animated, and hopefully encouraging people not familiar with the series to go read the manga. It seems to have failed you in that second point, and I'm really sorry that it did.
