“There’s no genre quite like episodic television. And no connection quite like the link between us and a show we’ve loved and lost. That’s because a TV series creates an ongoing and hauntingly plausible fictional world. It entices us to make a major emotional investment, it gradually and inexorably draws us in deeper and deeper, episode after episode — and then it turns around and dumps us, swiftly and coldly, with no right of appeal.”
