I think it's more complex. NBC wanted to do Star Trek again, but the current stock of show business talent is very politically motivated. Even if NBC tried to do a 90's Trek show, they would be eviscerated by critics for not including themes of race, class, or gender. It's not even the shitty writers and producers doing obvious self-masturbatory self-insert schwarbage, although that is a big factor. The problem is that Hollywood went from trying to avoid political or social controversy to embracing it so as to curry favor with increasingly pseudointellectual critics. Consumers, who want to feel smart, copy the pseudointellectual gobbledegook of critics and are afraid of looking unintelligent to their peers, so they can't even watch TNG and enjoy it without rambling about its lack of current year sociopolitical bloviating.
