Wandavision far outperformed my expectations going in, even if it may have fizzled out a bit at towards the end. But the show was always in place to setup the rest of the timeline going forward, so it's easy to look past an average finale.
From my perspective, Bettany and Olson may have hyped up too much. Bettany teased a cameo of an actor he always wanted to work with, which set the internet abuzz speculating who that may have been. And Olson teased a scene that would rival the a certain moment in the finale of Mandalorian Season 2. Bettany was trolling and I think Olson's words were taken out of context a bit, but regardless, I think they helped set expectations maybe a bit too high.
One of the most fun things about these week-to-week shows are the speculation, fan theories, online discussion, etc. But they have pitfalls of their own. I remember reading dozens of awesome GoT fan theories before the final season that somehow made the final season even more disappointing. And people nailed Agatha from about the first episode, which took away from that reveal a bit.
I'm not overly excited for Falcon and The Winter Solider, but I think Marvel has earned the benefit of the doubt in the material that they release. More than anything I'm just excited for a new weekly show and additional Marvel content. COVID has taken away that every few months new content that we got used to in previous years.
