TV’s episodic format offers unique opportunities for suspense build-up and payoff. Series like Breaking Bad, True Detective and The X-Files use cliffhangers, character-driven arcs and slow-burn mysteries to keep viewers hooked week after week. Which show do you think masters long-term tension like planting seeds in early episodes that pay off much later? How do pacing choices, narrative breaks between seasons and balanced subplots contribute?
