For its mid-season finale, Designated Survivor makes a bold choice: to spin its wheels a bit while it patiently waits for the moment when it can kill somebody off. Unsurprisingly, it’s not a great approach. It’s hard to earn any sort of catharsis when the big emotional moments — Alex’s death and Hannah’s shooting of Damien — are so undercooked. When a series prioritizes plot over character and relationship, that’s what happens. Plot happens, and it means almost nothing.
