I wish they had tried to replicate the original shot style and optical effects instead of trying to make it all look more "modern."
I agree with -SS- and disagree with Kor because with the current state of the art, computer artists have better tools for lighting and texturing than miniature modelers. In either case the artist can screw up with bad choices in texturing, lighting, blocking and framing, etc.
However, I'd change -SS-'s comment about "modern." I think CBS Digital was either rushed, or tried not to overwhelm the show with CGI shots that looked "too good." The flaw with that approach is that legacy 3D tends to look more plasticky and "fake." Today's rendering engines have radiosity, blur, depth of field and many other tools—provided the artist knows how to use them. If CGI looks bad (these days) it is not the fault of the technology, it is the failure of the artist.
I applaud the CGI effort—the new matte paintings look great—but I prefer the original VFX mostly because they "fit in." Too many of the new CGI "model" shots in space are jarring and push one out of the story.
