Technobabble. Modern Trek is improving in this regard, but they still have moments of cringe-inducing nonsense babytalk.
Speeches. TNG-era Picard and Michael Burnham are the worst for launching into long winded and completely unnecessary lectures.
Human interaction. TNG was terrible for the cast standing in a half-circle facing the camera, arms and back straight, taking turns to recite their lines instead of talking to each other in a natural and realistic manner.
Preplanning. ENT's Temporal Cold War could have been amazing if they put thought into it. Instead they made it up as they went along and it makes zero sense. Discovery's Red Angel storyline doesn't hold up under scrutiny, so the modern Trek lot have lots to learn too.
Money. Figure out how your future economy works, please. There's explicitly no money in some episodes, explicitly money in others. TNG and DS9 made it crystal clear there's no money, but

Picard is a rich man at the top of a wine making operation paying for a mercenary ship and one of his ex-crew is living in a shitty space-age trailer in Vasquez Rocks.
That error (if it is an error, "bird of prey"/"warbird" sounds interchangable to me) was originally made in ENT: "Broken Bow"I know its not healthy to nitpick Trek stuff too much but there are things I just cant help but nitpick my pet peeve for the series is when someone refers to a Klingon Battle cruiser or a BOP as a "Klingon Warbird" witch of course a war bird is a Romulan ship and i just cant help but groan when they keep bringing that up in relation to Klingons witch they do a lot in the Kelvin movies witch just makes me wince
