There is a behind the scene footage of one of the star trek voyager where one of the guys explains how gene Roddenberry wanted to incorporate as much real space science fiction into star trek as possible. I can't seem to find it. I may upload it if I get time.
Star Trek TNG was (according to him) his best interpretation of his Star Trek vision. He was dead before Deep Space Nine and Voyager came out. I think Voyager captured much of it, but right off the bat they started messing with the science. Bio-neural gelpacks? Why even bother with introducing that? It did not make the ship any more formidable than the Enterprise which did not have them.
Alas, in the NuTrek movies, all you have to do is push the deus ex machina button and whatever technology you need is magically integrated into the film.
