Yes it's wartime propaganda, yes it's so frightfully stiff upper-lipped, and yes it's full of stock 'ordinary' sailors puffing out their chests for King & Country. BUT it's so much much more than this, and well worth going back to and reassessing. First of all, it contains shards of true genius. Coward as writer and actor at his best - with a cast you could not equal. David Lean's eye, which means you get images and scenes that are as good as it gets (seeing the men run outside into the rain at action stations whilst a gun is wound out in readiness over them...following the journey of a shell from the hold up into the gun...). And with a subtle, telling story and writing that is truly great (a family picnic on the Downs with planes dogfighting overhead - modestly brilliant). And above this there is a certain essence - the essence of britishness, the essence of why we were able to fight the war how we did and who we are now as a consequence. I found it deeply moving at every turn, and 'true' in everything that matters. Just watch Celia Johnson as she picks up the telegram and knows she has to open it - just the tiniest hint of recoil. And a scene where the Captain shakes the hand and says farewell to each of his surviving men in turn - unhurried, eye to eye and hand to hand. I didn't expect to respond quite like this - but there is something great about humanity distilled into every frame of this great work.
