So Missy is back, and she still doesn’t want to rule the universe anymore. She doesn’t care much about power. And that’s so really OOC for the Master, because being power hungry was such a main distinctive trait for the character. It was the Master’s curse, in a way. And now, apparently, it’s gone.
Missy has the power to stop the planes mid air, and what she does with it? She basically just uses it to get Clara’s attention.
Missy is on Skaro, she could attempt to gain control over the Daleks, and what’s all she does? She runs around to save the Doctor’s ass like a companion (and he doesn’t even thank her.)
I know people love her for her sassy one liners and innuendos, but the Master, as a character, isn’t supposed to be just a comedy relief. The Master is supposed to be also a main threat. To the Doctor. To the universe.
But Moffat wants the Doctor to be the dark and dangerous one, so the Master has to be just another one of the sassy female celebrities who fancy him: Elizabeth I, Madame de Pompadour, Marilyn Monroe, Cleopatra, Nefertiti, the Pope aka Tasha Lem, River Song.
That’s why Missy doesn’t call herself the Master anymore, she doesn’t want to master the universe anymore.
