I'd say with WandaVision I actually enjoy the old sitcom elements way more than I expected to. It's not great art, but I'm comforted/cheered by them. In contrast I think the mystery aspect is pretty clear and I think if you have a certain level of say, comics and genre fiction knowledge you won't be surprised by what happens in that aspect in the first two episodes.
I'd say its in the third episode it starts to do more with the mystery (not enough but its starting to) and the sitcom elements I liked went down and I noticed their absence, although I did like things starting to be approached (not exactly revealed or spun in the incredibly unexpected ways, but approached).
And honestly even though I have a pretty good idea on where the mystery is going I've been enjoying actually talking/reading other people's thoughts on what could happen week to week, maybe because I haven't done that for a while.
