Went to see this last night with the missus and wasn't really expecting much. Once the first half hour was out of the way (a bit too ponsy, in a Brideshead revisted style) , it turned out to be a real belter and even our stroppy, difficult to please daughter was impressed. There is some first rate acting and the scenes shot at Dunkirk during the "tactical withdrawal" are particularly impressive. As a bonus, Keira Knightley ends up in a soaking wet outfit which shows off her lovely pins - but, granted, she does need to seriously consider surgical enhancement up top! Highly recommended (the film, not Keira).
