WandaVision has the potential to be the best thing they have ever done with the Marvel licenses/IP. You can only have so many costumed dudes punching other in the middle of the street, I'm glad they took the slight risk of making a show based on some of the better written comics that are slightly out of the mainstream.
That said, I can easily see people expecting super heroes doing super hero stuff, and getting bored. I just hope it does well, and the Falcon/Winter Soldier show is also less... straight comic-movie? But the latter will probably be a straight-up action show.
