Most of modern StarTrek is pretty much up there, especially Discovery, as that wasn't just bad by itself, it also seriously fucked up the timeline beyond repair and utterly failed at actually doing anything interesting scifi wise. It turned a franchise that used to be thought provoking into mindless pewpew with lots of crying and a complete lack of competency and professionalism. The "fan service" is also excruciating, as it's just name dropping things from MemoryAlpha, while completely failing at doing anything interesting with them.

I give Lower Decks a pass, as that at least understands StarTrek, doesn't mess with the timeline and actually continues where TNG/DS9/Voy left off. But most of the rest should better be snapped out of existence.

It's especially depression as we are right now in a time were serious progress has been made with AI and where a bit of though provoking scifi could actually work quite well, instead we just get reruns of old tropes.
