It seems what will cause a kid to watch a show he doesn't want to watch is parental disapproval. If he's been told it's too scary, too adult, or forbidden, his natural curiosity might cause him to want to learn WHY. My kids, with the freedom to turn things on or off, turned LOTS of things off, or colored or did Lego or played with dolls or action figures during "the boring parts" (often happening to be the adult parts—what did they care?) and only looked back up when happy music or light or dogs or kids got their attention again.
