I care about 2.39:1. I wish everything was in that aspect ratio. I'd crop Star Trek to that ratio, but it cuts out a little bit too much, so I'll settle for 16:9. I care about this bluray because the remastering makes the show look a bit more modern, and 16:9 helps with that even more, in my opinion...
Removing a big chunk of the picture and destroying shot composition is not modern, it's backwards.
