I think there's two ways to look at the episode. On one hand, if you're more interested in plot development or actions sequences, this episode will be kind of a letdown. On the other hand, there is a lot of character building and emotional development going on in the episode.
A lot of what we know about Wanda up until WandaVision has been through what we know about her from the comics. She hasn't been considered one of the main Avengers, so she hasn't gotten the spotlight like Tony or Cap. We've known enough about her story to keep the main plot moving along, but not much else. A lot of the past episode isn't giving things we didn't already know, but how the felt and impacted Wanda. Her pain has been weaponized throughout her appearances in the MCU, but it's never been dealt with. Not to mention, her relationship with Vision and WHY they connected was never really explored. We just assumed it was meant to be, because, comics. Her creation of the Westview Hex, as it turns out, is a direct effect of the traumas she's been through, but therapy, in a way. An unhealthy way, as we've found out, but it seems that's because she's never been given a heathly outlet, except for her realtionship with Vision.
I'm going to give them the benefit of the doubt and assume this emotional infodump will have a lot to do in the finale. It wasn't the most exciting episode, but I think it may have more importance than we know yet. (Maybe.)
