For a show that was supposed break away from the bog standard Trek formula of the Captain is the lead and the rest of the cast are the senior staff and bridge officers, this show stayed true to it, for the most part. Okay, the captain really wasn't the lead, but the captain is still in the main cast, or was anyway. The rest of the cast consists of the XO, chief of security, chief engineer, and now the head science officer. And in the supporting cast we have a medical officer who basically serves the same narrative purpose of a CMO except for a throwaway line stating he isn't.
Okay, the bridge officers aren't in the main cast, but aside from that they're basically getting the same amount of attention as characters like Mayweather or Harry Kim got.
I didn't watch much of Enterprise, but Harry Kim got a lot more attention than Detmer, Ariam and, um, those other three whose names I don't remember.
I think the greatest 'missed opportunity' of this season revolved around Prime universe Georgiou. I liked her a lot. I wish the Klingons hadn't killed and eaten her. She was great. MU Georgiou can be fun to watch, and she has some good moments, but I much prefer the prime version of her. MU Georgiou's best moments are when she briefly seems like prime universe Georgiou: when she seemingly intends to sacrifice herself to buy Michael time to get away; when she declared Michael 'lost'; when she briefly pretends to be teaching Michael something. Unfortunately, even when MU Georgiou (I could just start typing MUG instead, but... I won't) is supposed to be pretending to be Prime Universe Georgiou, she doesn't spend much time acting convincingly as the prime version.
In season two, I would like to see a third universe version of Georgiou. It can be the universe in which everything happened the same except that she didn't recover in time from the Vulcan neck pinch and Michael succeeded in her mutiny (or whatever you want to call it). Somehow, Third Universe Georgiou and Third Universe Michael both survived that incident. The point would be to get Prime Universe Michael to work her way through lingering emotions about the event and to help break the bond with Mirror Universe Georgiou, who is no doubt going to cause a lot of problems in the Prime Universe.
In season three, they can introduce Fourth Universe Geor... ok, perhaps not.
