Use of this trope can stretch credibility when the situation really can be summed up in only a few words. If you need somebody to run away, "No time to explain!" really saves you no time versus "There's a bomb!"
Well, no, whereas I can get my wife to move with "no time to explain" an equally pithy explanation of the actual facts will lead to oodles of lost time as I am asked how do I know this, what makes me so sure, am I not mistaken, who would have put a bomb there, etc etc
