But again, there comes a point where one has to accept it's television and it's never going to be realistic.
It's not so absolute. The goal is not to
be realistic -- the goal is to convincingly
seem realistic. The goal is to get
enough right that the audience knows you've put in the work and are thus willing to trust that your poetic license serves a purpose and isn't just laziness or stupidity. You want to make it as easy as possible for them to suspend their disbelief. Like the old joke goes, the key is sincerity -- if you can fake that, you've got it made.
It's obnoxious to assume that storytellers are automatically
entitled to the audience's suspension of disbelief. The audience isn't obligated to accept a damn thing if they don't want to. It's the storytellers' obligation to
earn the audience's acceptance. After all, we, the storytellers, are the ones providing a service to the audience, not the other way around. Our job is to try to satisfy them. And it's up to the audience where they choose to set their standards for satisfaction.
But to be blunt about it, these shows aren't made for people like them.
Why the hell not? That's also obnoxious, that attitude that certain segments of the audience don't matter and it's okay to alienate them. That's not only inconsiderate, it's self-defeating, because you're arbitrarily settling for a smaller audience than you'd have if you tried to be inclusive of everyone. Good storytelling should have something to offer for everyone. Again, the goal is to satisfy as much of your audience as you can, and that means being aware of the diversity of viewpoints and preferences within that audience. Better to set up an open tent than to build impassable walls.
Do you know why
Star Trek became such an enduring hit while pretty much every other 1960s-1980s science fiction TV show bombed? Not just because ST was more inclusive than most of its peers when it came to racial and gender diversity, so that women and nonwhite viewers felt represented rather than alienated, but because it put in enough work to make the show smart and credible (at least relative to the total idiocy of most other genre shows) that the portion of the audience that valued credibility
also felt represented rather than alienated. That's why ST was such a hit with the science fiction community, why they embraced it and promoted it like nothing else before it -- because the SF community at the time was mainly a fanbase for prose SF, which on the average put far more care into its plausibility and intelligence than the SFTV or film of the time (or most of it since). Believability wins you a larger audience, and there's nothing bad about that.
