You know, I guess I'm of the opinion that if they're going to spend time and money on a soundtrack overhaul and remix, they should just go all-out. I mean, keep the dialog stems and original music score, obviously, but use modern techniques and matching sound effects to make a balls-out, Oscar-worthy caliber 8 channel mix. Just as long as the original track is also available in lossless. Most of the time they just steer the original mono mix around a little bit, put a bit more bass punch in, and call it a day.
While they're fixing these issues, they might as well completely re-do both T1 and T2's soundtracks with TLC into really awesome 8 channel mixes and really make them shine. My biggest pet peeve is that Arnold's pistol sound effect sounds like a little toy squeak gun. Give it some power and heft, for godsake! He's a killer cyborg!
