Good but problems

Rating: 8/10 (19 May 2018)

I found the Dunkirk a good movie, but the end was a waste. The RAF Fighter pilot who lands his Spitfire on the beach, sets it afire & then is captured. The British naval officer who stays behind. These two did nothing but get captured by the Nazi, depriving the Allies of their much experience & knowledge. I do not understand what point was trying to be made with these two examples.
