Ozu was an amazing filmmaker. He strips down filmmaking to the bare essentials, leaving so much room for character development and interaction. His minimalist approach allows him to become one of the masters of the character study on film. There is little to no camera movement, a wholly uncomplicated plot, and simplistic edits. I find it hard to think of any other director who relies so much his characters to get his point (and themes) across.
His work is an absolute joy to watch.
