I guess that would be anyone interested in character development rather than the kind of 2-dimensional characters seen in TOS. After 72 episodes, no one on that show got a promotional as I recall. And while the bridge was diverse, it was loaded with stereotypes. I found Michael's journey engaging, not just her Starfleet career but her backstory as well.
Good character development generally stands out in my mind because the story builds a character to meaningful, memorable moments where we see their growth through false starts, actions, imagery, symbolism, rebirth, etc.
I can't think of one single moment in which Burnham learned a single thing which was conveyed to the audience in a gripping, believable, emotional, memorable way.
This show tells rather than shows, and that's not a good way to present character development (or anything else really). Burnham gives lengthy speech, log entry, or internal monologue proclaiming to have learned something, then proceeds to unlearn it in the same episode, repeat. Remains 2-dimensional. Maybe 2.1-dimensional after 5 seasons (which can be said about most other Trek characters).
Given the chance to do it all over again she'd still start the Klingon War.
