I was just changing the channels when I saw they were showing a movie I saw in a class about 2 years ago, Voces Inocentes. I didn't have the heart to watch it again, the first one was enough to have a huge impact in me.
It's about the war in El Salvador in the 70-80's, more exactly how the war was viewed in the eyes of a kid (his family, his friends). Its a cruel reality (don't remember if it was a true story, but the events of the war there, those did happen), that shows how war is such a useless event in which the innocents are the ones that end up paying the most.
