I really can't stand it when miscommunication is used as a plot device. I find it to be a cheap, hokey trick to create drama when there isn't any.
Miscommunication only works when you have characters who are so stupid or impulsive that they will act without thinking and never check in before it's too late.
Sure, I can see it being based in reality, but reality is stupid and obnoxious (if it wasn't, we wouldn't read for escapist fantasy). The kinds of characters who would be in a story of miscommunication are the ones that I have no desire to root for. They are fools whose only problems are ones of their own making.
