blindness
The Music Of Silence lacks emotional weight, developed characters, a coherent linear story, and sufficient enough acting to make a passable biopic of a living legend.
Devoid of any subtlety and bereft of a strong plot, the fact that a film so reductive as Blind was made this recently is quite shocking.
It may not be one of the most technically efficient documentaries ever made, but Hearing is Believing is certainly one of the most heartfelt.
