Re: Earth based Trek show
This is a silly argument. Star Trek has become more than a literal interpretation of its name, its a brand. Are you also prepared to argue that Star Trek IV and Star Trek First Contact weren't real Star Trek movies because they took place almost entirely on Earth?
Having an episode take place on Earth here and there is far different than setting the show on Earth.
