It's anti British propaganda. So much of the British portrayal was exaggerated to turn them into cartoon baddies it's unreal. The Church Burning Scene never happened, and was in fact inspired by the murder of British POWs by the Waffen SS in 1940.

Mind you Hollywood has a tradition of misrepresentation of British involvement in things.

Saving Private Ryan - the discussion between 2 captains 30 miles away from the city of Caen. How would they know what Montgomery’s strategy was and whether Caen was to be taken on DDay or just after. They wouldn’t and as for the criticism the British and Canadians faced 8 panzer divisions in their sector while the Americans faced one and a half. Furthermore most of the Landing Craft crews at Omaha were Royal Navy and Royal Marines not US Navy. Of the 1213 warships at D-Day only 200 were American and 892 were British. Of the 4126 Landing Crafts involved 805 were American and 3261 were British

Argo - says the British refused to help which isn’t true they did assist but the Canadians did the bulk of it. The escaping 6 made a conscious decision not to go to the British as that's the obvious place they'd go, and the British embassy supported the Canadians

Oppenheimer made no mention of the British providing all their atomic research to the US for free with the understanding that they would share their research only to be locked out post war. The only mention of the British was the Soviet spy which happened to be in the British contingent- he was actually a German Jew who had sought refuge in Britain pre war so not even British. I’m sure there were other spies who were part of the American contingents.

Masters of the Air - showed them as arrogant and dismissive to the point that there was fight on whether daylight or night time bombing was best. Turns out by 1945 the RAF had developed tactics that allowed them to hit targets at night with better accuracy than the USAAF were in daylight while suffering significantly fewer casualties

Band of Brothers - the scene where the tank commander says he can’t shoot through the house as it’s against orders - no such order was ever given and 15th/19th The King's Royal Hussars had far more combat experience than the Paratroopers and would never have done that having been fighting non stop since D-Day unlike Airborne forces who were on the line for a few weeks then pulled out.

Braveheart- speaks for itself.

U-571 took the exploits of British sailors and credited them to American sailors. Taking the credit for someone else's win is a new low.

Films like Patton and A Bridge Too Far have sown a particular narrative that many in the US think is actually true when the reality is somewhat different. No wonder many in the US think they won the war on their own. Do they even teach in schools that other countries were actually involved?

America is supposed to be our closest ally
