Although the film has a running time of two hours+ ,for it tells the story of a man's entire life ,from his enlistment (and even before) to his old age,there is never a dull moment .
John Ford was one of the most wonderful storytellers that ever was.The first part of the film is made of trivia,but everything is endearing ,moving .Take the dad's and the brother's arrival:no syrupy violins and choirs needed: the Irish are doing Mary's cooking justice and they are not in a hurry to hug Marty.The same goes for Marty/Mary when they fall in love:what could be more down to earth than this kitchen ?And however something vibrates ,as the love they all feel for the country they left behind.
The second part deals with wars and if the tone has changed ,the spirit remains intact:what could be more prosaic than burning Mary's toilet to celebrate the end of WW?Although the hero experiments tragedy ,Ford always avoids pathos and melodrama: the child's death during the celebration is given a sober treatment.Mary's passing is perhaps the most beautiful scene in the whole movie,being Fordesque to the core (remember the death of the mother in "three godfathers") and her fleeting reappearance at the very end of the movie is not irrelevant.
A life is made of small joys and big griefs.
