I’d been postponing seeing this film for some time. My hesitation stemmed from knowing the plot beforehand, which can sometimes detract from the experience. However, I recently watched it and, considering all the buzz surrounding it, I have to admit I anticipated something considerably better. It's true that the movie is technically well-made; the acting, cinematography, and other aspects are superb. Sadly, that’s about the extent of its merits. My initial thought was, where did the massive budget disappear? *Dunkirk* involved nearly 400,000 soldiers and countless vessels, yet what we see is a limited number of soldiers, a few boats, and just three spitfires facing off against a bomber and two Fock Wulfes. To make matters worse, we’re essentially shown the same event repeatedly from various perspectives. This feels disrespectful to those who made the rescue possible. There are a couple of characters you can root for, such as the Navy commander and the older man on the pleasure boat assisting in the rescue. The rest of the cast seems either unstable or unintelligent. The film’s commitment to realism is questionable. Take the scene where soldiers are trapped in a boat being riddled with bullets—would anyone genuinely believe they could patch dozens of holes by hand and then sail across the channel? Then there's the spitfire that runs out of fuel and seemingly floats indefinitely over the beach, apparently for some scenic shots. At other times, relatively large boats sustain damage and capsize in mere seconds. I also would have appreciated a bit more background information or setup. Instead, the story jumps right into these meager numbers of boats and planes struggling to reach their destination. It’s quite a letdown overall.
