if it's a good dub: go for the dub, if not then go for the subs.
it's a visual medium, you HAVE to appreciate that while your are reading the text you are going to be missing out on some things that happen on screen.
You also have to realise is sometimes the dubs can be far better than the original audio, Kaneda is far less whiny in the English dub of Akira and let's not forget David Hayter's legendary performance in Metal Gear Solid, even though not an anime. In fact the English voice cast for MGS1 sounds a hell of a lot cooler than the original Japanese dub.
See I am REALLY pissed at these people who are obsessed with the "purity", they are fucking idolaters, they treat the directors like gods and act as if their work is beyond improvement.
Well Bull-fucking-shit, George Lucas is living breathing proof that even great minds can go INCREDIBLY astray. Artist worship is precisely how Kojima and Lucas are able to make trash sequels, they think they can do no wrong.
Films, anime, video games are COLLABORATIVE works, and yes they CAN be improved on with edits and if they can they should. The idea that everyone should always kowtow to the "great and all knowing auteur" is bullshit in my opinion. I hate "auteur theory" it fundamentally undermines the way humans are actually creative and constructive and especially undermines video games which are highly collaborative works.
Yes, within a single project there should be someone with overall control, but they cannot be a dictator about it, they cannot be beyond criticism or be impossible to tell them they are wrong or could do it better. Imagine if Red Letter Media had been Lucas' producter as he made the Star Wars prequels?
Games can and should be modded, books should be translated, motion pictures should be redubbed. The original works should not be destroyed, an they don't have to be in this infinitely copyable digital age.
That doesn't mean EVERY change is good. Like colourising black-and-white films is pointless as they were shot, framed and balanced based on everything being in greyscale. And then there is the censorship angle, self censorship like Spielberg digitally removing guns from the federal agents' hands in ET. Oh and not to mention the shameful tampering with Star Wars: A New Hope
That just shows how the "pure vision of the Director" is far from infallible.
They say for an artist to make a great work of art you must first let him make it then bash him over the head and tie him up to prevent him adding more and destroying it with a thousand little "improvements".
People need to be open to how other people can add more to a work and at the same time the original crew can undermine their own work by obsession and second guessing their own decisions.
I mean trying to fix it so that Han shot 2nd... it turned out worse than if that is how the scene had originally been shot.
