Disney should have released the first 3 episodes together. Some viewers may have tuned out after the first 2. It wasn't until the 3rd episode that you got glimpses what the show might actually be about. They had to have episode 4 like they did to keep people watching, and even hopeing for positive chatter to have those who tuned out already to come back.
Also, if you haven't you should watch the two episodes of Marvel Legends before watching WandaVision. They are focused on who and what Wanda and Vision are.
