this one is a bit stupid, but as a child I was mad for 'War Films' .One Sunday I watched 'King Rat', about a Japanese prisoner of war camp. In one scene, there's a guy with a little dog, who gets loose & kills chickens, they kept for food, the prisoners then killed & ate the dog. 50 years on & a life long dog owner, what disgusted my 5 year old self, still does today, never watched that film again. I know over the years ,as I aged, I have seen much worse, but the impression made in my childhood still holds
