This is a decent film, there will be arguments over accents, location and facts but this is the film industry. You will never find a film which truly tells the story correctly from all points of view. If it says based on true events then please realise its likely only 10/20% accurate, look at the Crown.

Back to the film, its a good pace and never drags which makes it an easy watch, I wouldn't say its gripping or life changing its just a simple film, just don't assume this all facts.
