This is a witches-centric show, and it is full of revelations and twists for the continuity of mcu. As a direct sequel of WandaVision, it is recommended to watch it and then dr. Strange Multiverse of Madness to grasp the lore of Agatha All Along.
And unlike many superhero movies, the story is not about crash, boom, bang, good guy bs bad guy, the good guy wins and gets the girl, it's not that kind of show. It's about a some women and a boy who use mind power rather than brute power, hence we are actually need to digest the story mindfully layer by layer, because so many times things aren't what they seem to be in this show.
And we do have a cunning, devilish, morally ambiguous main character, so, what's not to love?
