I love watching documentaries. Basically I "watch" them every day, since I always have some kind of documentary playing in the background on my tablet when I go to sleep.
Latest one I watched was Carl Panzram: The Spirit of Hatred and Vengeance. Carl Panzram was a serial killer and all around bad guy who was hanged in 1930. In his lifetime he managed to do thousands of crimes and eventually wrote a memoir about his life in prison.
Fascinating guy with nothing but hatred for mankind.

Do you guys and gals like documentaries and if you do, what kind?
