I personally do not agree with hiding faces: to me, demanding not to have faces shown on camera is not-so understandably. Moreover is visually disturbing. Not as much as the perpetrated acts of war and revenge (?!) committed by soldiers, but I appreciated the conversations regarding ethical issues involved. Unfortunately, I didn't see the very end, due to a shortage of time. Hope to have soon another shot, anyway.
I liked the dialogues between the former soldier and his girlfriend. The soldier asks his girl friend: "Did you forgive me?" She says: "It is between you and yourself. You and the families of the Palestinian man you killed". If only every killing act could be questioned like this.
