I don't have much time to respond so I'm going to just hit one bullet for now:

Are you going to try to argue that Khan and Gul Dukat weren't given nuance and development? Some of the things that made them such compelling antagonists is that we were given insight into their motives and backgrounds and perspectives. Khan absolutely was nuanced and the persecution and illegality of genetically enhanced humans was a great stepping off point for him. Just about every antagonist that pops up in Star Trek gets some kind of explanation why they are doing the things they are doing, and the crew takes a moment to acknowledge their inherent worth as living beings and, if they're sentient, discuss possibilities for negotiations or nonviolence. I haven't forgotten that Klingons, Ferengi, Borg, Cardassians and many others start off as villains, but we are given many opportunities for them to be "humanized" through characters like Worf, Quark, Hugh/Seven, Garak and others. There are no "good" or "bad" aliens in Star Trek.

So keeping that in mind, how did things go with the Ba'Ul? How did they handle Control? What nuance was Lorca given? In Discovery, your first impression of a bad guy being bad is always correct.
