While watching Saint Seiya, lostsatyr and I have come to the conclusion that the way to indicate characters are truly suffering in a shonen series is apparently to have them bleed all over the place. How else to explain the massive amounts of the red stuff? And this was a kids' show!
Of course, we're of the opinion that showing the kids the consequences of fighting might actually dissuade them from trying out things they see on TV. I After all, I can't ever recall hearing about Japanese kids getting injured when they tried out something they saw in cartoons. American kids, all the time.
Maybe there's something in that...or maybe it's just my wishful thinking.
