I think it's completely possible to enjoy a flawed creation.
And in this case, I think La'An's story this season was fairly strong, even though it was heavily (if not entirely) tied to her relationship with Spock.
Ortegas got an entire episode devoted to her, but the criticism about her experience with the Gorn being largely overlooked prior to that is completely fair.
Uhura certainly had less to do, and I think Una was pretty short-changed this season.
Sure, I think the key is balance in all things. I absolutely loathed the third season of "Picard", but I'm not going to jump into every conversation about it I see just for the sake of saying so.
But if it makes sense, and is relevant...I might, if I feel like it. There's room to talk about what you disliked about something, and why. It just shouldn't be your entire personality, y'know?
