If Starfleet characters would never act like that then unfortunately that's a rather sad commentary on how Starfleet officers actually act, which could be fairly stiff, unprofessional or just downright unrelatable, not like people.the complaints I see so far from the people who disliked DSC and Picard, is that it's childish and a cartoon. That starfleet characters would never act like that.
It's funny to me, not to drag another topic in here, but I mentioned that I found the idea of Geordi being with Leah Brahms and showing up in PIC would be creepy given how the relationship as presented. And I just reviewed the transcript is so illustrative of unprofessional behavior and that Geordi is somehow in the right. That's how Starfleet officers should act? O_o
