Hi Breda,,About the mediation on morality, i dont have special ideal about it and i never think about his film from this aspect, i like ozu`s film more from viewer than artistic study,and frankly speaking i am not interest in film study.
but as before i mentioned we can found out hundrends of study paper about ozu`s film. i repeat some fragments study from others : in his film ozu set the father as a god position, taking everything just smile/ never angry/ always merciful，
audience can from this view study the patriarchal social system in asia ,
you also can study the position of female in his film
in his film there is big part of morality concerning, but not much exist in his personal life, what a pity for a master.
