Wow. I went back and watched the second episode again, from the start (without Mrs. Orbert, who possibly has bailed on this show).
The first episode had references and homages to countless black-and-white sitcoms. The living room is the Petrie's from The Dick Van Dyke Show. The musical theme incorporated cues and callbacks to Bewitched, I Dream of Jeannie, I Love Lucy, and probably others. Those are just the obvious ones. Kathryn Hahn as Agnes the neighbor is Gladys Kravitz plus every nosy neighbor cliché character, plus some unidentified weirdness. Mr. Hart was Darrin Stevens' boss Mr. Tate merged with a few other "boss" characters, including Mr. Slate. Even Mrs. Hart was Ethel Mertz, Lucy and Ricky Ricardo's friend, give or take a few other clichés. It was like they put all of these ingredients into a blender and somehow a cohesive screenplay came out, though obviously it was the opposite; it was a very carefully crafted blend of all these ingredients.
Episode 2 focused more directly on the Bewitched parallels (including the awesome opening credits), but also upped the weirdness factor. This is where Mrs. Orbert bailed, but right where I was finally starting to get sucked in. I'm still not sure what to make of it, but we're getting stronger indications that things are not as they seem. Well, yeah, obviously, but what are they really? Wanda kept asking Vision, as though she really needed to hear him reassure her, whether this was all real. And I'm pretty sure it's not (we keep hearing someone ask "Wanda, who is doing this to you?"), but have no effing idea what reality is.
I have the feeling that Episode 3 will explain a lot of things. And probably crank up the weirdness factor some more.
