Since the original poster already received his answer, and is already set on viewing it. I have been meaning to post a review (without spoilers) since the first response.
Foremost, it’s a Christopher Nolan film, he doesn’t make mistakes. This is the same man behind the Dark Knight trilogy and Interstellar. With that knowledge, the title, and action packed advertisements it’s pretty obvious what most viewers expected.
Expectations were far different from reality with this film, it plays more like a documentary than action film. That’s not necessarily a negative thing, it gives real perspective into one day at Dunkirk. Anyone that has never served in an operational theater, most troops don’t get the “big picture,” they just see one piece of the entire puzzle.
This film lets you see one entire day from the land, air, and sea (in that order). Now, the reason I didn’t find it interesting is because… The film is called Dunkirk, a battle wherein over 100,000 were killed or captured. Just on the allied side alone. But don’t expect to see much of that, this film was centered around the evacuation. As the film ends it feels like a second half is about to begin.
I’m not dismissing the film, it’s brilliantly done and has a very proud British feel from start to finish. Even a veteran that from this battle* said it felt like he was there. It’s just my opinion that if they made a film 70 years from now about an entire day fighting in Southern Helmand, even with a view from our air assets, intel officers, allied troops, adjacent companies, etc. it would still be a boring film for most.
