Cowboy Bebob for example...the english cast does a great job, and I just can't watch too much of the Japanese Edward.
heh... i can't watch too much of edward in any language.
cowboy bebop got by with being high budget in the USA. steven j. blum is now mr. i'm in every high budget anime and video game for US release. however... jet and faye's voices in the US versions are really weak.
in the japanese release... all 3 main characters basically got one of the most famous voice actors in asia.
