I always thought the episode of twilight zone, "to serve man," was really sad. They were so happy, trusting and had no clue what was waiting for them and they just were going to be used like cattle for food. Especially at the end, when that guy gets so hungry, he is like 'fuk it!' and just gives in and accepts it because he is so hungry. It made me bawl and cry out loud, 'why? oh why must we suffer?!!!' with my proverbial fist in the air. I felt so sorry for him. What would his mother think?
