@gohan6425 there are VERY minor changes, a few scenes and while one is a fairly big one, it is largely in part the same and recap
@emdier IT NEED to be done. People need to know. That did Attack On Titan which is thew same thing. And even E& which was for the most part SAME thing it NEED to be Dub.
You are also comparing something that was dubbed locally to something that would need to be farmed out to BANG! ZOOM! (read a lot more expensive) to be able to use the same voice actors, and please don't bring in the Akito the Exiled argument into play. As that was an entirely new side story, while this was for the most part a set of Compilation movies.
