That's the thing for me. I grew up during the Cold War when those movies were a thing. I've seen this movie too many times already (throw in Dr. Strangelove too) to be interested in seeing it again.Those who enjoyed it more will probably also dig the two FAIL-SAFEs from 1964 and 2000, THE BEDFORD INCIDENT, CRIMSON TIDE, BY DAWN'S EARLY LIGHT, DETERRENCE and TWILIGHT'S LAST GLEAMING.....
