Yes, dubs do butcher stories. And if they don't then they look retarded cause they don't fit the mouth movements at all. But it's one or the other.
Why? This happens in native-English cartoons as well. It's just something that you have to deal with when you're watching something that's animated. Japanese dubs don't even go along with mouth movements all the time. Your point is moot.
List of good English dubs (imo, subjective remember?):
Cowboy Bebop
Hetalia
Monster
Vampire Hunter D Bloodlust
FLCL
Ghost in the Shell
Every Studio Ghibli film
MS Gundam: 08th MS Team
Ms Gundam: War in the Pocket
Samurai Champloo
Death Note
Code Geass
Fullmetal Alchemist: Brotherhood
Do I have to keep going, Blanko? You satisfied? I'm interested in your witty retort to this baited answer.
