Too many “what got cancelled too soon” questions, what’s a show that went on too long?
Hard mode: no The Walking Dead
The very first episode she attacks her commanding officer and ultimately gets her killed. Her direct involvement in starting the war that killed hundreds of millions is up for debate.
She continually puts her own opinions first and ignores or undermines direct orders, and those around her if they disagree.
There’s precedent in other Star Trek shows where the violate orders which are obviously wrong, but the ones she breaks aren’t.
And despite being raised by Vulcans, she has the emotional control of a 12 year old.
An awful character, and definitely the fault of the writers and not Sonequa Martin-Green.
