When Gene Roddenderry made his first pitch for Star Trek, studio executives rejected it because it was "too cerebral". And indeed it was, it asked questions about morality, how to deal with other civilizations, people who have different cultural values to us. It was indeed science fiction. Science fiction is not just having "futuristic stuff" in your story, it's about asking questions about the impact of technology. In this way, Blade Runner was science fiction. Yes, it had drama, explosions, and lots of running. But it also asked questions about the nature of humanity, and the morality of treating replicants as subhuman. It showed that if we lose our humanity, the future would be grim.
The rot started with the Star Trek reboot. They tried to turn it into an action flick. A lot of running, a lot of explosions, a lot of action. Star Trek was NEVER an action flick! And then STD and now Academy is trying to turn it into a vehicle of political messaging. About the only thing the current series has in common with TOS / TNG / VOY / DS9 is the name "Star Trek". It's not science fiction, and the writers don't seem to understand that. It is a shallow teenage flick.
