What a dull film, two hours watching a bunch of extras stood around on a beach. The usual British bashing, poorly portrayed as either cowards or mindless and paranoid. There is no story, no likable or relatable characters. There's little action, tension or depth, no one seems in any great rush (boats just sit around, drinking tea waiting to get sunk. The disjointed time frames are not clever but annoying. It's so cheap too hardly any boats, five planes and crappy explosions, beautiful blue sky and a lack of effects. No one hardly says a word, it seems so amateur. The last 10 minutes is OK. The actual story could have been so much better, with a good script and director. I think of great war films "Saving Private Ryan", "Hacksaw Ridge ", "Fury" and regret that this is a missed opportunity.
