TOS was filmed in full screen, so there would have to be some tampering in order to make it widescreen. I would think this would also be the case with TNG, DS:9, and Voyager. It made sense to update the special effects of the original Star Trek (because they wanted to re air them in HD), but I am not sure I would see the point of doing the same to the others. I mean honestly, when is enough enough? Can we not accept that a show or movie is from a certian year and enjoy it as that? Things like special effects will ALWAYS be getting better, does that mean we have to constantly be upgrading them in every show and film? George Lucas has fallen into this trap. SW has already undergone two special effects revisions, and I daresay they won't be the last. The idea of a work art never being finished is a futile one, if that is the case how are we every to enjoy it? Might as well say, I'll check it out later, when it is finsihed and no longer a work in progress. Let it be done and enjoy it for what it is. This is Star Wars, a film from the late seventies, notice the model work and the special effects? They were top notch for the day...
