Watched it at imax in town last night. Great film but thought the beach and sea scenes could have used more CGI to give the illusion of the sheer size of the operation. We had lines of troops waiting for ships to arrive numbering about 200 troops. There was 400,000 in and around Dunkirk! The flatilla of boats were in there thousands too and yet we only saw a handful. So too in the sky. We had three spitfires and that was it. Maybe they didn't have the budget to beef up the numbers a bit either through CGI or in extras etc. Still, don't let it put you off. Really good to see a BRITISH war film though. We just need a decent WW1 British film now. A top blockbusting Battle of the Somme please.
