I’ve almost finished season 10 of MI 5, one of the most gripping and intelligent TV shows ever made. The plots seem real and are full of surprises, with each episode a cliff-hanger. In fact, every episode is so riveting it's extremely hard not to keep watching the next one without interruption. Many characters—people we really care about—are killed off, giving MI 5 a hard shell of credibility. There's no room for sentimentality, as we feel ourselves being dragged ever more deeply into Harry Pearce's tense spy world. A revival supposedly is under consideration. Sure hope it happens.
