The tech that they used shouldn’t have existed in that form. They shoudn’t have had visual communication, they shouldn’t have had transporters (even if it was “new” tech in the show), they shouldn’t have even had phasers. It should have been as the past was described in “Ballance of Terror.” That would’ve made the show more interesting as it takes place in the past from a TOS perspective.

And yeah, Voyager sucked too. The only Voyager character that I like is the Doctor, which is why I only like watching episodes about him. I think his plot in the episode “Real Life” is the best thing to come out of that series (which bothers me even more because they kept interupting his meaningful moments with some dumb and unnecessary sideplot that destracted from him in very jarring ways).
