I have been late to Ozu, but when I finally did I couldn’t forgive myself for not doing so earlier.
I started off with Tokyo Story and it was obvious why he is such a respected filmmaker. His realistic exploration of the human condition and how he crafts his films speaks for itself. His stories follow human relationships in transitional moments, youth and adulthood, life and death, love and loss in the most undramatised realistic form. Almost as a fly on the wall voyeuristic documentary style.
Technically considered a rebel and his films challenge on conventional rules in cinema. Below is a brief video essay on his work.
