Well yeah, I have a problem with it, since so far in NuTrek, it's only the black women main characters that have been characterized that way (which I've mentioned in my first post, thanks you for not mentioning that, otherwise I would have thought something else). Side or recurring characters, like Owosekun (had to search her name on memory-alpha since I won't memorize everyone), Gabrielle Burnham, Bryce, barely have any characterization, they're probably the descendants of Travis Maywether in term of characterization. Culber has some characterization, except he is better know for dying and getting brought back than anything else he ever did.
What other characters have acted unlikeable? That McCoy-lite doctor from the asteroid, what was her name, Jean Reno, Jett Reno, whatever? She is rough and has sass, but at least she's not completely unlikeable. She's cliche and gets annoying sometimes, but didn't do anything that stupid to deserve enough "hate". Po? I guess you could make a case for her annoying personality, but then again she's royalty, so I guess she wasn't meant to be "normie" or to be liked. Cornwell? She's more of a bureaucrat, like all the Starfleet admirals before, so she doesn't have that much of a distinct personality. DIS characters range between unlikeable, shallow and forgettable, with only a handful of exceptions.
Also, remind me again, how did Burnham atoned for the mutiny? By bringing back the evil version of her dead captain who is nothing like her? By becoming a freakin' time traveling Iron Angel or whatever it was called? By going 1000 years into the future and reforming the Federation?
Here's the thing. In any character arc, the character must grow or change, or at least feel differently at the end of the arc, but based on how the actions affected said character. Since that's how you can see that said character has responded to what he experienced. Otherwise you get the impression that they learn nothing, they experience nothing and they don't react to the world.
How have any NuTrek characters changed in any significant way? The only one I can think of is Ash Tyler, in some ways.
