Detachment (2011) on Netflix

In Director Tony Kaye's Detachment, Academy Award® winner Adrien Brody stars as Henry Barthes, an educator with a true talent to connect with his students. Yet Henry has chosen to bury his gift. By spending his days as a substitute teacher, he conveniently avoids any emotional connections by never staying anywhere long enough to form an attachment to either students or colleagues. When a new assignment places him at a public school where a frustrated, burned-out administration has created an apathetic student body, Henry quickly becomes a role model as a teacher who actually cares about the well-being of these students. In finding an emotional connection to the students but also fellow teachers and a runaway teen, he finds that he's not alone in a life and death struggle to find beauty in a seemingly vicious and loveless world.
