If you didn't watch the MCU films that lead up to WandaVision, I would recommend watching the "Marvel Legends" episodes for Scarlet Witch and Vision, since they basically feed you the portions of the movie which set up the series. It's part of the Disney+ subscription, which I signed up for on Friday to watch the show. Personally, I loved the first two episodes, which is hardly a surprise since I grew up on the MCU source material. While I feel like I have a good "sense" of the what and the why for the series, I am curious to see how the story plays out, and particularly the impact on the characters...particularly the ones being introduced (in some cases, reintroduced) in the series, which is said to tie directly into the next Dr. Strange film. After the year off...it's nice to have something Marvel to watch again!
