Well my first total experience with that is Sailor Moon. I never was aware at the time that it came in japanese until my interest in anime grew to the point where I was paying attention to the language used. Yeah, its funny cause they leave out a LOT of information (heaven forbid someone swears). I don't really mind dubbed anime, but lately I've been watching subbed anime, and my boyfriend (who doesn't like anime) can't figure out why I have no problem reading and watching anime.
My theory, be glad you get what you get and dont be too analytical.
