Re: Nahh, the old Star Trek was for nerds...
If they had had CGI then (or much, much more money), you would have seen less reuse of existing movie sets. Being feasible within the budget was a big constraint, and ideas had to be reworked to use what was available.
While not all scripts were of equal quality, the number of very good ones is high. Many scriptwriters today are too arrogant and too ignorant at the same time, and not only Star Trek ones. The appalling quality of many productions is a direct result of that. CGI attempts to fill the void, but works only for children and very 'naïve' people....
