I'm glad to see they've become so meticulous. I watched Arrow's Dawn of the Dead last week, and while not awful, it definitely needs a new master. Perhaps it's the best they could get their hands on at the time.
Sound is just as important to us. Just as we want to present the film's images as closely to its original theatrical release, the same goes for the audio. Our preference is to always prioritise the original audio presentation - whether it be stereo or mono - over any new remixed, or redesigned audio version. We make these newer versions available on our releases, but never at the expense of the original audio, which remains our main priority.
I wish more studios and authoring houses took this approach.
