WandaVision is an absolute masterpiece in it's own right. Instead of the usual action packed like films that Marvel has produced over the years, WandaVision slows itself down a peg and mainly focuses on how a character with world changing abilities deals with grief.
Mystery, drama, action, comedy, heartbreaking scenes, Vision and his meaningful lines, Wanda never getting a break. Name it, WandaVision has it. If you haven't seen it, I highly suggest you go watch it as it is one of the best cinimatic pieces that Marvel has produced.
