No offense intended Iron, but your son's fiance seems very impressionable and perhaps a little slow in that she chooses to believe what she hears and sees but not research it any further.
It isn't the movie's fault that she chose not to get real information on the situation.
I have a friend, he always tells me things he "hears"... and passes them off as truth. I rebuttal with "Not sure, don't think so though". Nine times out of ten I can tell that the information is BS before I look it up, but I do it anyway just to be sure.
The only thing dangerous is the inability for people to question what they hear and are told, and then go and actually find out the information for themselves. Its out there, all over the place - its very naive to accept whats being fed to you as truth.
