Former Royal Marine Cassidy Little, who was blown up in Afghanistan, has his say on the military blockbuster.
We all trust Christopher Nolan to tell a story.
If you don't, you've not been paying attention to his movies.
He revitalised Batman, he created the cult film Memento, and modernised space travel in Interstellar. So it is no surprise that Dunkirk is one of the most anticipated films of this year.
Here is the good news. It is a really good movie.
But the bad news is, it ain't a great movie.
The film 'Dunkirk' is the fictitious story of the evacuation in 1940, told from different perspectives.
It is told from the air, through Tom Hardy, through the sea, with Mark Rylance and Cilian Murphy, and on land, with the help of Fionn Whitehead.
These perceptions are a snapshot of what was happening during one of the biggest failed military campaigns in British history.
Nolan does what he does best, and messes with the chronology of the film to allow the story to have a larger impact, while climaxing at the same time.
Not to mention that it is a relentless movie!
The combination of the special effects, action sequences and stunts - all happening one after another - is almost overwhelming.
It is beautifully shot, and the performance from the actors is good as well.
Even Harry Styles, who makes his acting debuts in this film, is not distracting from the overall story and sense of abandonment you get on the beach.
I got distracted a couple times while watching it and this shattered the illusion and broke the flow for me.
Some of the lines are a little too Hollywood. You will know them when you hear them because you will find yourself groaning, and wondering why.
Also - and I hate to do this - but we have to compare it to other war films to establish a benchmark. What we want is a Saving Private Ryan with the Union Jack tattooed on it.
The first half hour of Saving Private Ryan almost perfectly immersed us on the beach of Normandy.
In Dunkirk, there was none of that.
Yes, you see some men getting blown up, but the true carnage of war is not found in this movie... No body parts, no blood in the water, nothing.
There are a couple bodies, but there are supposed to be thousands of people dead on the beach, and I really didn't get that impression.
Maybe that was because they wanted to keep the film PG, or maybe it is simply because Nolan is not known for his gore, but I felt it was missed.
I also want to bring up that it got me thinking about our modern soldier.
In a day and age where terror attacks are on our streets, and the advice from our government is to run, hide and report, we are given a film about the British public who sailed across the channel to pick up soldiers who were being left to their death.
It seems there might be something we can learn from those early, civilian heroes. What I will say, is that it left me with that 'feel-good' feeling.
And on the big screen, with lots of sound, it is a sight to behold. In the end, it is very much worth the watch.
Get down to you local Forces Cinema, as it is doing the rounds, and pay the money to see it, because you will like it, if you are interested in war movies or not.
And on top of all of that, I think there is already an Oscar buzz about it.
