Are we really getting so prudish that we aren't allowed to see good looking people wearing less clothes in movies these days? Do we have to go back to stealing Dad's Playboys from under his mattress?
People go to see SF movies for all kinds of reasons
. Some want explosions, some want a philosophical story, some want humor, some want solid characterization - and some fans just like seeing great-looking, fit, healthy male and female bodies in very tight outfits or less.
TOS was infamous for all of the above. A movie based on TOS should reflect those elements.
