Violence certainly gets censored as well, Umineko had mosaics blotting out the most bloody of things. And I hate fake steam! Oh well, that's why they put stuff on DVD to get rid of that.
Kari Wahlgren and Crispin Freeman, both of them do a good job in whatever they happen to be in. I usually like the Anime they happen to be in as well, so that helps.
This show always irritated me in the way they had him not actually be Superman, but still have him have all the friends he had as Superman and fight all the enemies he had as Superman. So frustrating... be Superman!!
There's plenty of childish Japanese Anime and there's plenty of adult Western Cartoons. There's literally no difference between the two mediums other then vague perceptions.
