A perfect movie ruined by an irritating soundtrack score

Rating: 9/10 (22 July 2017)

I was eager to see this movie before word of mouth circulated. I managed to catch it at a preview showing a day before general release. I saw in on the large screen with Dolby Atmos.
The film was breathtaking and the aerial photography were some of the best I have ever seen in movies. OK we are in the digital era but the blending of the real and unreal (topped with lots of shaky camera work) was very impressive.
Other reviewers have highlighted the great acting, great period costumes and makeup, and great (authentic) locations. So I ask Christopher why, oh why, he ruined a masterpiece with a ridiculous contemporary pulsating beat soundtrack that relentlessly played virtually throughout the whole movie. There were plenty of sound effects and those would have held the movie without something not remotely in period. This was made even worse near the end when the music built up ready to burst into some great British anthem (Land of hope and glory / Enigma variations / etc) and fizzled out with something inappropriate. I wondered if he was trying to capture a younger crowd. At my session the audiences age would have been 35 plus.
Anyhow this Dunkirk should be a must-see for all ages.
