Personally, I'm in wait-and-see mode.
Despite the SJW hand-wringing over it, it's a very real factor if NK will accept a woman as leader, or the internal power structure/struggle will. And even if they would, it's not clear if she has the pull to take the leadership position. If Kim is dead or comatose, her power base might be gone.
And as to if "she's even worse than he was" I'll wait and see. Those leaking that info or rumors might have an axe to grind. Considering NK's history, "worse" could mean a lot of things. A dragon lady who ruthlessly consolidates power internally could just as easily stabilize things. Since she was educated abroad, she has to be just as aware how behind NK is as even compared to China, much less South Korea.
