the soloist (2009). directed by joe wright.

the soloist (2009) confirmed the truth about mental illness; that you can't FIX people. especially when they are mentally ill. you can't fix them medications, with motivations, even good intentions won't work. may be all you can do is be there as a friend. 

as experienced by steve lopez: (writing his newspaper article) "I can tell you that by witnessing Mr. Ayer's courage, his humility, his faith in the power of his art - I've learned the dignity of being loyal to something you believe in ... believing without question that it will carry you home!"

another movie with a raw take on mental illness, watch spider (2002)
