Those who aren't deaf may find themselves in deep revolt against everything Artinian is saying. Yet the singular power of ''Sound and Fury'' is that no argument that gets made in it is remotely dismissable. Peter's story is contrasted with that of his brother, Chris, a hearing person who intends to give his deaf little boy the implant.
The film, which immerses us in a blazing interfamilial war, engages issues of freedom, devotion, and identity that are nothing less than religious in their implications. It's a work of intimate and wrenching humanity.
