I started watching Doctor Strange in the Multiverse of Madness (not yet finished, no spoilers please) and I don’t understand the motivation and anger of Wanda. I believe I have watched every Marvel movie including the first Doctor Strange, although I have not seen the Wanda Vision series. But I remember very little about her.
Now I am considering pausing and re-watching a previous MCU movie to get some context. The question is, which one? And, optionally, should I bother?
