I enjoyed it. Quite a lot, actually. Avengers: Age of Ultron gets sneered at, quite a bit – a bit too much, in my opinion – but it set up this series nicely. WandaVision actually mined quite a few of the mid- and bottom- tier MCU flicks for characters and concepts, usually to the show’s benefit. There was some good dialogue written for this show. Also: there was one particular scene that made me almost yell “BEEP BEEP, MOTHERF*CKER” at the screen, so there’s that, too.
Bottom line is: I didn’t waste my time watching WandaVision. I had a good time. Just bear in mind that I watched all the movies. I don’t know how comprehensible it was to people who didn’t, although my wife’s liking the show, too.
