Maybe I haven't hung out here enough
Yeah, this debate has been going on here since they first aired. You joined more recently, so I get why this may sound strange...
Are the new VFX not generally produced by fans for fans at CBS Digital and widely praised both by fans and creators alike, but especially by people like Nimoy and Justman?
Yep the people who made them were fans and they did try to capture the feel of the original, but they were working fast and on a limited budget and CGI on a limited budget looks less than stellar and dates VERY quickly. TBH, some episodes look great. The Romulan ship in Ballance of Terror is spot on. Balok's cube is perfect. The shots of the Enterprise in the atmosphere in Tomorrow is Yesterday is sweet (and the new finale actually makes sense). I can name a few other episodes where the effects look really good. But more often than not, I get pulled out of it because it looks off. Mostly when they strayed away from the meaning of the dialog (a few times in The Doomsday Machine), went in a direction they wouldn't have on TV (the EXTREME close ups of the Enterprise) or the finished effect looked cartoony (the Fasarius dwarfing the Enterprise). While I get that 60's effects don't look good to younger viewers and HD ruined the composites, the old shots still looked organic to the series.
Now....not everyone feels that way. And yup, most people who have never seen the original effects are probably just fine with it. But as someone who has grown up with the series and never felt the effects were inadequate, the original effects will always be my preferred.
As for the sound mix: again, if you didn't grow up with or were accustomed to the original, you won't care. But I miss the original mono mix, which is NOT on the majority of the episodes, regardless of what Paramount claims.
As for Justman and Nimoy, they were people with opinions. I'm sure they were fine with them because, unlike Star Wars, 99.9% of the effects didn't change the meaning of the episodes or scenes and they enhanced the value of the series for future generations. However, there's also a generation of SW fans who have never seen the originals, so it's moot for them.
Having said that, if Paramount/CBS had really invested in top notch effects work and really made them look great and more organic, I would be much happier. It was a nice try but some of the fan films and You Tube takes look better than the official release.
But your milage may vary. It's an opinion and a preference, not an argument.
