Wadavision is one of the best mcu projects, especially fans of the comics will have a great time finding the little clues in the first few episodes that lead to the villain but also to smaller details. The first two episodes however aren't the thing what you expected, but you'll find yourself enjoying the show at least after episode 4. Wandavisions follows the story of Wanda Maximoff (Scarlet Witch) after the events of End game. This series also includes some reference to House of M (marvel comic) and many hints to marvel comic characters. Everyone who loves a show that isn't to revealing will love Wandavision too, although you should've at least watched the mcu movies including Wanda (especially Infinity War and End game) to understand some character decisions.
