Yes, I didn’t end the show 100% feeling in agreement with Wanda or her actions. I understand them, and I even heavily sympathize with them, but she did some horrid **** by taking an entire town hostage. The narrative went back and forth a bit too much to concretely say whether she acted knowingly or not - I understand she started knowingly (while not willfully in the burst of emotion at finding the deed and lot) - and then the scope of her power and its effects likely got the best of her. She basically deceived herself. She knew what she was doing, but not necessarily the full effect it was having on all the unwilling participants.
Clearly she’s the protagonist, but not necessarily the hero of the story. I don’t think she’ll be a “hero” moving forward either. It’s kind of exciting to enter MCU anti-hero territory because up until now everyone has had a side to take in their respective movies, and their actions can be easily classified as “good” or “bad.” This show opened up the MCU to morally ambiguous characters - which could be a very good thing for “realism“ and “grittiness” and such post-modern concerns, but would simultaneously lose a bit of the charm and innocence of traditional tropes of ”heroism” and “goodness.”
Generally speaking, it’s not good or bad; it’s just a new direction. One can have personal opinions on what matters more to them in a superhero epic, but opinions are just that. Personally, I tend to side with the mythical archetypes and appreciate the Captain America-types. Doesn’t mean a good Cable or Wolverine story doesn’t get you going though. Everything in doses and moderation.
