No offense, but I call bullshit. TNG's model work was fantastic in most cases, and extremely well done. I've watched many an episode over the years, and I think the visual effects hold up quite well. Sure, there's a lack of certain things, like the ability to show tons of ships when an armada is supposedly going into battle, but what is on the screen looks good. Frankly, I find a great deal of the televised CGI work done in the later years to be quite wanting in comparison to TNG. Sure, TNG's visual effects will need to be re-done if they want to do an HD release, simply because they were shot on videotape and don't have the resolution necessary to support HD. But I don't think viewers would otherwise have any problem with most of the visual effects from that series.
