Spouse chooses ghastly crime (Investigation Discovery channel, Homicide Hunter show, for instance) and other sensational programs (such as My 600 Pound Life and Dr. Pimplepopper). They run on a loop, so he will watch programs he's seen again and again. These shows involve him intensely and often he talks back to the TV. He has an active social life, so that's not an issue. He watches Turner Classic Movies as well as political shows, such as Rachel Maddow's, so the range of programming is not an issue. The level of interest is. Would anyone else have observed a person glorying in crime and circus sideshow subjects?
