Most recently:
Bundyville - Season II - The Remnant - more in-depth coverage that builds on the Bundy-Standoff covered in Season I - this time more about the christian right wing nutjob-spectrum, Aryan Nations, Marble Country and the politics attached to all that - ends in a bit of a lecture but is otherwise rather informative and well made.
Crackdown - monthly episodes covering the drug war from a perspective of the drug user - focus on the Vancouver, Canada downtown east side, interviews with users, lawyers, housing advocates, medical researchers etc. - informative and challenging in a way that makes you question your outlook on substance use, addictions and the layers and layers of politics and governance in a supposedly liberal country.
