Okay, before you click away, I'm not talking about the really "R34" type of stuff, nor am I talking about the extreme gory/violent stuff either.
I'm talking about incorporating darker elements into stuff without actually resorting to violence and sex.
For example, I just read the special "Skyward Sword Manga" at the back of Hyrule Historia (U jelly?) and all that Hylia says to Link and just everything in general is pretty emotional and moving (it was to me at least). Yet, there was never that much violence. Sure, there was a little blood but still.
Another example would be the Pokemon Adventures Manga. Just go read the Ruby/Sapphire/Emerald Saga to see what I mean.
So, my question, for all the people who can give an answer, is this: how does Japan get away with it? Why is American media bashed on the moment they step out of line?
