During my long medical treatments, I watch a lot of Turner Classic Movies. (It's the only commercial free station they get at the clinic, and the ads on daytime TV are just too depressing to endure.)
To watch TCM consistently is to be constantly reminded that there was a time when people were uncomplicatedly patriotic, had hope for the future, believed in democracy, trusted government, and tried to do good. (There's also quite a bit of casual racism, and sexist nonsense about the scandal of divorce; so it goes.)
I've worried about the constant drumbeat of paranoid themes and conspiracy theories in popular culture since the days of The X-Files and probably before. But watching TCM does help you focus on what makes Star Trek Star Trek, and what's wrong with unsatisfying versions. Good Star Trek is utopian, optimistic, and otherwise values oriented towards a vision of human and social goodness. Bad Star Trek has been tainted with conspiratorial thinking and is full of flawed characters and an untrustworthy and dishonest Federation. It's the failure to get it that makes more recent incarnations unsatisfactory.
