Go see Dunkirk.  Seriously.  I can’t say much more as I don’t want to spoil it, but go see the movie.  Good cinematography, acting, scoring, and pacing.  Yes, some rivet counters have complained about nitpicking things like the destroyers, Ju-87s’ sirens, and the actual Bf-109s used.   (No, I’m not joking.)  Ignore them and go see the movie posthaste.
