JJohnson was talking about a specific frame (linked) where the model-ness is very apparent.
I understand, and I honestly don't think it looks bad there. It's interesting to find out that the new klingon shot is a matte painting and not a CG render. So far those in favor of CG have been claiming it as an example of how good it could look. In actuality the only CG is most likely the warp shot and that's unanimously bad.
Funny how lock step Okuda is on "Original Intent" as he's the guy who swapped out several ships in TOS-R with more modern looking stuff- especially the Tholians that look like the designs from Enterprise.
