The new audio IS very modern sounding in dynamic range and sharpness. I don't hate it, some is a bit over the top and artificial, but it has a bit more bite. I just figured that Taolar sweetening it.
Also, and maybe it was the speakers I was listening on (which do have their bad days), but I found myself turning the volume up pretty high for some scenes and down for other. Just me?
I'll drop 2 other concerns from Part I while I'm thinking of it:
When Clarke jumps out the Daily Planet window and his clothes fade change into Superman's as he falls... what power is that exactly? I hate to request an effects shot but any chance of adding some fast-motion-like blurring limbs or rapid spinning as he falls so it looks like he might ACTUALLY be changing clothes not just willing them to transform?
What was with Otis' black eye? We lost the explanation for that (cough or I got distracted cough). (I don't remember what it was originally.) Can it be added back (or (heh heh) the removed)? I suppose it can be shrugged off that the guy's an idiot and he just got his in trouble somewhere.
