Not yet. It was fine in the movie admittedly. They worked miracles with the camera angles to bring out its good side. Rising from the rings of Saturn worked very well, I seem to recall.
Looking the model on my own terms, I see more far more ugly than beauty. You have be very forgiving of its appearance. In other words, this is your U.S.S. Enterprise if you've never lived with the others for any real length of time. You can see beauty, where I just see parts of the original or film model that are missing, in the wrong place or at the wrong angle.
