Seems there are many "studio inspired" positive reviews here. This is certainly no 10! First, the film should have carried a "historical fiction" disclaimer as most of the events depicted never happened. Second, the Munich agreement didn't "buy time," in fact after Poland was invaded and Britain declared war on Germany, there was no war. The peaceful interlude, called the "phony war," bought time to prepare for war, not Munich. I suppose this propaganda was made to rehabilitate Chamberlain's image. Meh.
For a truly historical account of these events watch Darkest Hour (2017).
