Dunkirk is a belter of a film. It looks like a war movie but it's built and directed like a mercilessly taut thriller that just gets more intense as the Stukas and U-boats close in. It's going to win a stack of baubles come awards season, and deserve them.
But if there's anything the Internet loves to do, it's pick holes in something beautiful. That goes doubly for when a film covers a subject that has a legion of experts (real and self-appointed) ready to show off their encyclopedic knowledge. There aren't many subjects that prompt such a flaw-finding frenzy as the Second World War, and legions of sharp-eyed buzzkills have duly descended on Dunkirk to pick out the errors.
Many of the inaccuracies are errors of omission, including those forced by Nolan's budgetary and time restrictions and desire to avoid the brain-rattling thunder of Saving Private Ryan's beachfront carnage or the brassy explosionfests of Pearl Harbour. Some on the other hand are just old-fashioned anachronisms.
None of them can detract from what Dunkirk is - a cracking film, though-provoking and intense, with an impact its mistakes can't lessen.
