She's horribly self centered and vacuous. She complained about the silliest things, and provided very little support as a friend or romantic partner.

Just bad. The narrations of her articles never made sense, she always wrote about the same thing.

Every episode was the same thing. She realized, but never learned.

Whoa ... this is such a valuable statement.

It's something I've been thinking about a lot recently. We know things, but don't really understand them.

I also interpreted your comment as an insight about superficial awareness that doesn’t translate into a changed consciousness.

...yes. Carrie would "realize" things, but she never learned what about those revelations was important in a way that would change how she behaved towards others. She never learned or grew as a person. Who she was in the last episode, was exactly who she was in the 1st episode

Totally agree! I think the reason she didn’t grow is because the show is a counter-narrative to traditional views of womanhood. Perhaps if Carrie had evolved, she would have drifted closer to what women are expected to be (kind and caring), which threatens the underlying premise.
