I've given anime a second look though, because I've needed something in 22 minute segments with standalone episodes yet an overreaching plot line that comes to a properly planned end. Luckily, I stumbled into two excellent series, one of them being Samurai Champloo.
I've read that Japanese reserve makes acting difficult, therefore they put all their emotions into animation. It seems true in this case; young Mugen here shows some complex but common human emotions. If he's the offender, he has a "Suck it up, that's life" attitude, but if he's the one who has been wronged, only revenge will do.
Um, he's the only one who knew where the pirate treasure is. I'd want to die too.
