Does it matter that TOS
clearly diffentiated between sub-light and faster than light travel and propulsion systems
spoke of the need for artificial gravity
clearly pointed out 'Earth-type' planets as being the focus
reffered to space in 3 dimensions when plotting course
referred to nebulas, black holes (stars), quasars
clearly spelled out the difference between our galaxy and other galaxies
created a beautiful funtional (looking) bridge for each specialty--nav, helm, engineering, science, comm..
showed plauible looking med tech--hypospray, biobeds, hand held med scanners
spoke of the difference between carbon life and possible other types
Yeah, I think it made a huge difference.
Well, TOS is certainly to be applauded for getting all that stuff right. I guess just don't attach as much importance to it when it comes to ranking the shows.
I find TZ and TOS of equal merit, each with their own fair share of classics and clunkers. And, honestly, at the end of the day I don't really care which one had the better science.
When it comes to science fiction, I'm just more interested in the "fiction" part . . . .
