Edited anime is horrible, its like castration...
(SPOILER ALERT)
They took out the Hot-Springs episode from Cartoon Network because it was full of fan service. :\ Even though it was it had IMPORTANT shit happen to, mainly with the caster and shells, and how Gene gets that kick ass ammo for the last stretch of the show.
(END OF SPOILER)
American and censorship, its just as bad as Japan! I mean with Japan they get away with "alot more" then on the hentai they blur and pixel out the bits. -_- Not cool.
With America there is so much censorship, coddling. Cause no one will EVER find out what sex, violence, or anything else extreme in their lives. *eye roll* Don't even attempt to give me the "They are to young" BS. >.> Freaking censorship ugh.
In anycase I perfer whatever I watch first for sub or dub.
Most animes I like dub, but that usually pertains to older animes.
As one of the oldest/older person on this forum (I assume this), I watch older anime, Saber Marionette J, Ah! My Godess, Tenchi, Slayers, Aria: Zeriam the Animation, and many more classics, the voice acting was really really good. Of course some companies do it better than others as well. Some voice actors can ONLY do one role in my opinion as well... like the voice of Gai from Martian Succesor Nadesico, not only was his quality in Sorcerer Hunters low quality, but I just couldn't see his voice fit the role of Carrot.
Some anime just fits better sub, or dub, some is good both.
I perfer the better job done usually. Also some companies do try really hard to make sure everything fits, and the job is done well.
