I thought she would like it simply because of the age of the film, but when I turned to see if she approved, she was fast asleep. I changed the channel anyway. I wish I hadn't now. What I saw was this: An old black and white Mexican film featuring a woman singing a melancholic and slow tempo song and in the background you can hear a person crying terribly, kind of like how you'd imagine a person would cry knowing that they're about to die at the mercy of a twisted serial killer.
