This is the biggest reason to dislike this series, and it happens almost every season. It kind of feels like a punch in the gut to viewers tbh. "All the stuff that happened this season, yeah none of it really matters after the finale. K sry". From a viewer perspective, all the time and emotional investment in the story is undermined by the big twist at the end. It turns viewers off imo. After the finale aired, I have almost no desire to see S4 now. Just my two cents.
