The idea is, a woman with supernatural powers creates a pocket universe, which takes the form of a TV show, in which each episode is a different decade. So the show makers get to do a tribute to the styles of the 50's, 60's, 70's, and so on, as they develop the plot of why this is all happening.

Unfortunately, the big plot takes place in the Hollywood Superhero universe, in which everything is dumb and predictable except for the inevitable Big Twist about who is on which side of a dumb black-and-white morality.

Also, none of the episodes are as good as the shows they're paying homage to, which makes me think we aren't really in a golden age of television.

The best thing about Wandavision is Kathryn Hahn's performance as the nosy neighbor, and she's done a lot of stuff better than this.
