I love documentary film. When I first saw the 2003 documentary Touching the Void, it aired on PBS. I sat there with my soda and popcorn and watched the film. It was so harowing, that when the critical moment came, I had my legs up against my chest and I screamed.
It never got nominated for an Oscar. It is one of 10 "best documentaries never nominated by Oscar" (according to Indiewire, which oughta know).
