WandaVision not only marks the first original series from Marvel Studios on Disney+ but also one of their wilder entries in the larger Marvel Cinematic Universe. Though it seems like in context the entire thing is playing out in a bubble somewhere in New Jersey, the fact that its sitcom inspiration is 100% canon but also viewable on TVs within the MCU shows how different it is from everything that came before. That said, there were still things that they thought of while creating the show that ended up not making the cut, but in the end the show itself is weird enough without some of those ideas.
