Does it mean it's a genuine remix?
There's an oxymoron for you.
On genuine I mean it doesn't introduce new sound effects and places the old ones where they should be in the space by looking at the movie. So a good remix which is faithful to the movie's original intenion. But I suppose it's clear how I meant it anyway.
Well, according to IMDB, there was a theatrical 6-channel mix. I suppose it's possible that this new mix is simply that 6-channel mix mapped to a 5.1 arrangement, and the reduction in dynamics is just the result of whatever home near-field mix logic they currently employ for their audio. But I don't think that's very likely--I suspect it's a whole new mix, that, AFAICT, doesn't muck up anything but the dynamics--and even there it's not horribly flat, just not as good as the Laserdisc, that's all.
Also interested in the true video source if this isn't DCP-sourced after all.
