Mine is that Discovery should have been a series taking place in the Picard era.
Star Trek just isn’t good at big wars. Single battles where “Oh shit there’s a borg cube coming” can be tense and exciting but I’m way more into the ethical dilemma or space mystery mind screw episodes.
I think that’s the main problem with Enterprise. Someone fresh out of Voyager’s writing room said the phrase “temporal cold war” without thinking about what those words meant first, and then they said “Fuck it, let’s go full Starship Troopers.”
