I mean, I think the premise of Falcon/Winter Soldier is just less interesting on it's face. There was a huge mystery/intrigue factor with Wanda Vision (plus the sitcom gimmick in the beginning) that just isn't really present here. If other people are anything like me (seems unlikely) the lack of interest is just because the show doesn't seem all that exciting (and to be honest I don't think the cast is as strong either).
