I was just exaggerating about Wanda using profanity and getting into it with Vision. But I have no problem having them fight in their show. Pretty much all couples do it, and it's a natural thing (even between a witch and an android). Sitcoms love that kind of conflict. I think the writers will treat Wanda just fine on Disney+. Jac Schaeffer doesn't look like she would be interested in accepting ANY ideas from Byrne and Bendis in her work. It would go totally against her previous comments about making "big, positive statements." She even stated how excited she was about working on female-centred stories, so I have high confidence in how the show will portray the Scarlet Witch. She explicitly mentioned that she was not interested in adhering to comic canon that is discriminatory in any way or that violates her values systems (a lot of fanboys vocally objected to these sentiments apparently). I'm actually a little bit surprised that you don't seem to have as much confidence in Schaeffer as I do, to tell you the truth.
I guess we look at things different. I just get the sense that the whole Wakanda salute stuff wearies Boseman and he is more interested in doing indie projects. I feel like he is a little bit overwhelmed with the whole Black Panther phenomenon. And he recently lost a LOT of weight. In his press conferences he comes off as really reticent and reserved, unlike Bettany and Olsen who are bubbly and funny. Doesn't mean he's not enjoying himself, but his statements about not wanting to do any Disney+ projects and that of all the things he was excited about doing in the future, none of them included franchises shows a certain lack of interest to me in his Marvel endeavors. Maybe I'm way off base, but that's my feeling.
I thoroughly enjoy serious dramas by the way! I'd say a decent majority of the stuff I watch today are documentaries on PBS and often times the subjects they cover are not pleasant ones. In fact, some of them are downright sad. But I like them because I learn a lot from them. I just think superhero movies should be more lighter in nature. I watch the MCU ones because they have a good blend of action/adventure, comedy, special effects and heartfelt moments. And it's easy to watch them many times over. I mean, you literally can NOT have a bad time watching those old pre-MCU Sam Raimi Spider-Man movies because of their cheesy campiness. Whereas I couldn't stand watching the Amazing Spider-Man movies because of their total lack of humor and complete absence of any sign of life (they almost killed my interest in Spider-Man to be honest). But that's because the writing, editing and pacing sucked in them. So I say dark themes can work very well in dramas which I often like. It's when they try to go gritty in superhero films, I usually lose all interest. Because they usually go overboard with that stuff. Even the Batman/Joker stuff of the past fifteen years seem like dramas to me with some superhero elements. And those kinds of movies, in my view, can often lead to OVERACTING, which is REALLY annoying. You don't get that kind of thing in the MCU which I like.
