In an interview on Jimmy Kimmel Live!, Paul Bettany explained how the show will evolve from the sitcom-style to a full-on MCU action movie. The Vision actor confirmed Kimmel's theory that the sitcom-world of the show will not make up the whole storyline. "That’s 100 percent correct," said Bettany. The actor went on to say, "We hurtle through the decades, and we hit different genres of sitcoms and then Vision begins to think that this is getting a little weird, you know. And in the end, you end up in full, MCU action movie."
With less than a week before the first MCU series premieres, Disney and Marvel Studios have remained tight-lipped about the show and how it connects to the MCU. Though much of the details have remained a mystery, Bettany's comment is not the first hint at the action-packed show. Teyonah Parris, who plays the grown-up Monica Rambeau, called the show "a full-on action movie, mixed with sitcoms."

There were a few references to SWORD in the first two eps. I’ve seen a theory that the neighbors are villains from the comics. Agent Woo from Ant-Man and the Wasp and Darcy from Thor and Thor 2 are in it.
