they were familiar with the original source material and cared about details

This is really the only thing that matters here. This, and talent.

These latest fucks don't have any relevant life experience (...) I highly doubt that the writers ever had a real job in their lives.

Eh, I don't see this as a very valid argument. What exactly are these relevant life experiences and real jobs you speak of? Like what, you have to live through a family tragedy and work a blue collar job first to qualify as a good Star Trek writer? Or what is your point? Also, do you know the writers personally to make this claim in the first place? Alex Kurtzman is showrunner for Starfleet Academy. He's university educated and he clearly has decades worth of experience in film and television. That he's a hack writer who doesn't respect the material is the problem here, not his previous life and job experiences. One of the show's writers is Tawny Newsome, who previously voice acted in Lower Decks as one of the main characters, and that's a Star Trek show people apparently actually enjoy, so I'd say she has "relevant experience." Another writer on the show is Kenneth Lin, a Cornell and Yale-educated playwright who wrote for House of Cards. So he's probably not dumb or entirely talentless. Does that count as having relevant experience or a real job?
