I don’t read critic reviews anymore, and everyone is different on how they want to be spoon fed details, so there’s never a Goldilocks zone on that. Was it not enough background of why she was sad, why she was the villain, or why an avenger was murdering people right and left? I know the answer to the first two, I don’t feel the third was justified, so that’s my problem with her portrayal. Maybe we’ll get Wandavision 2 and redeem her, or maybe Olsen wanted out of the MCU and this was a way to burn a bridge. Either way it’s a shame if we’re done with the character, especially like this.
