WandaVision
The first few episodes of this were a real slog, given that they'd made a sitcom homage/parody that was utterly bereft of comedy, but once it switched to the real world and the plot got going I actually found myself getting quite invested (even if I called the basic premise long before it was revealed in the show). Was nice to see a couple of supporting characters make a return to the franchise, but sadly my interest in this seemed to dip again towards the end. The concept was interesting, but overall the idea was way better than the execution.
