WandaVision is easily the most popular show streaming right now about a scarlet witch of vaguely defined powers living inside a vintage sitcom with her dead husband, an android named Vision who used to be Robert Downey Jr.'s robo-butler named JARVIS. Second on to The Crown, probably. We don’t know, we haven’t seen it. But the weird thing is, everything we just described is actually an extremely simplified version of Scarlet Witch's comic book adventures.
