The comics have utterly fucked Scarlet Witch, She-Hulk, and Wasp, pretty much beyond repair IMHO.
To Wanda, the concept of a normal, peaceful life is fictitious. She's also a lonely person who is very disconnected from people. Alot of people can relate to that. Interestingly, she is not portrayed as a "Team Mom"; every other Marvel female is "Team Mom".
Ironically, the narrative demands of feminism mean Wanda cannot ever be allowed to have the things she wants. Chthon is thus a kind of feminist.
The huge difference from the comics is they made her an actual Witch, whereas in the comics she is an amorphous blob of a plot device. This pretty much makes MCU SW not bogged down by endless eternal X-Men shit.
But the challenge they face with Scarlet Witch is the chronic lack of modern source material. The past 15 years of comics have been a near-total desert.
With She-Hulk they have alot more material, though she has not fared much better.
