I encourage anyone to think critically of the media they consume.
There is no A- or B-list comic book character more than 5 years old that doesn’t have something that many people will find off-putting. There’s no ongoing comic book more than 10 years old that hasn’t gone through rough, perhaps even distasteful, stages.
For some, that might make it difficult to enjoy the medium. I really understand. I’ve gone through years where I drop some of my favorite stories and characters because they’re being handled in a way that makes me unhappy. In order for me to enjoy them again I have to make a conscious decision to accept how they were written but decide it won’t define the character to me. Every comic book fan does.
So for me, I don’t find Wanda and Vision’s relationship (roughly 1970-2002) in the comics abusive. On rare occasions it could be uncomfortable, but it was consistently written positively in my opinion. Post 2002 there are many moments I do not like that arise from both of them. I made a decision to accept this and not let those moments ruin the enjoyment of what I liked.
As for wanting the MCU couple to play out in a way you determine is abusive–if their comic book relationship makes you this angry, and eager for the negative cultural impact of seeing one of the biggest movie events of all time glorify abuse, you should step back. Being invested in hate over a comic book relationship isn’t worth it.
