The most interesting part of the movie was that you couldn't predict how it would come out. It has less of the dislike of American military men (overpaid, oversexed, and over here) than was actually felt by British men in uniform, as well as those on the homefront who weren't just out for fun with the soldiers, and I suspect it was written to ease tensions that were almost to the breaking point. When this was made there was no way of knowing how long the war would continue so I don't think it was written with postwar relations in mind. I do know that a great many Brits even today are very hostile to the American notion that America won the war and saved the free world. Compared to their contribution, we were "johnny come lately"s to both wars. This movie tells us it was a cooperative effort and we should appreciate each other's contributions.
A touching aspect is the tie between the American who lost his father in WWI and the housekeeper who lost her husband in the same war.
I enjoyed the election when the woman suggested maybe they should have tried having a woman stand for that position instead of a man. Here, here!
There were short scenes of the worrying going on in the American homefront, to show families suffered in both countries. There was an American whose ancestor had come from that little town. To heavily underline that idea that we are very similar and can all get along was the American, flying a plane with a Brit, who married a Brit intending to bring her to the US and wished there were a bridge between the two countries--and the reaction wasn't that the fellow was a vile interloper stealing British women while their men were overseas. And finally a quotation on the screen if you hadn't gotten the drift from the rest of the movie. This should be titled Why Can't We Be Friends?
I might have given this a 10 but I got tired of the hammering home of the point. The fact that they felt they had to do that is an indication of how much Americans were resented in Britain, not just for their manners and culture, and romancing women with gifts of luxury goods they hadn't seen in a very long time (getting many pg) but also for being wasteful with food and supplies that British sailors were dying from U boat attacks to bring to Britain.
