I think you lose so much from dubs
i can't imagine patlabor without the voices of noa, asuma, and the rest
i've watched one dubbed eopisode and the entire mood and characters completely
changed, it wasn't the same.
And that happens to every anime i've heard dub for.
i usually watch the anime a second time anyway when i want to
just enjoy the visuals
watch these and i think it will give you an idea
