Engaging diplomatic drama, not overly dramatic A political / diplomatic movie that builds up nicely and hold ones interest. Shows the time period, few months before the commencement of WWII. We get to see the side of British PM Neville Chamberlain, and his negotiations with Hitler. Most WW movies are about the actual war and show how Churchill led Britain. This was a welcome change.
Also Hitler is shown to express some trepidation about the fact that his country's citizens are understanding his principles, but he felt they were not while heartedly with him, atleast didn't express it as vociferously, as he expected. This particular pre-war time period has been delicately captured.
Although there isn't a dramatic conclusive ending, but the Director chose to remain at the edge of the war (true to the title) and didn't venture into it.
Spoiler: There is a Valkerie like sub-plot also, but it is more nuanced, & perhaps at an early stage of planning, with less clear intent, as expectedly, war didn't commence till then.
