Time Travel
I think, for me, it's not time travel stories per se. It's how time travel is usually handled. There has to be structure, rules, and consequences for it to work within the larger universe. And Star Trek tends to do a giant reset button with only slight "winking" changes to the timeline in the climax.
I think when you make time travel too "easy" to do, or set it up as an option that could materially remake the universe the characters inhabit, then you basically have it laying around in the background like a loaded gun where the audience thinks to themselves: "Well, why don't they use [technobabble X from episode 27] and time travel to fix this?"
I tend to wish Star Trek would just retcon into the idea established by Star Trek (2009). Basically, the version of time travel the MCU has with Avengers: Endgame where causality is preserved. That time travel can't change the past of the timeline and universe you inhabit, but can only push the time traveler into another universe where those events occurred differently because of the time travel.
And I will say that Discovery introduced something that I really like, which is the idea that time travel and travel across universes is "unnatural" and your body will want to return to its own time. I just think it makes things more interesting when there's limits, rules, and complications.
