Well, I have been reading this thread. So let me replace the word "upscaling" with what? "Recomposit" from old 90's effects that I can produce better effects that on my computer?
They are rescanning all of the original elements into computers, and recompositing them 'with computers'. Do you not understand how much of a difference that can make? They'll have more control over the lighting, no matte lines, the ability to spruce up mistakes and planets with CGI.
Still gonna look terrible. Still gonna use the same 4-5 shots of the Enterprise flying by? uggghhh. Why even bother then?
The Enterprise going to warp in the teaser sure didn't look terrible, it looked fantastic.
If CBS had access to the original 'filmed' elements of the ships for TOS, I'm pretty sure they would have done the same thing. It would have been amazing to see what they could have done with the old TOS ship models with today's tech. They simply had no choice but to CGI everything in those instances, with TNG...they have all the film.
The reason for bothering? Well, the entire concept is to convert the show to HD...it's not some type of 'reimagining' of the show. Personally, I would like the show to be restored with all original elements, as it originally aired. This isn't some sort of revisionist project like the Star Wars movies...and thank goodness for that.
