I can't stop watching, but it's so frustrating to see the absolute blindness of these people who "didn't see this coming" when they should have been bowled over with red flags YEARS before the other person stated killing people. It's really hard to watch and not yell at the tv. An endless parade of oblivious enablers and naive doormats. It's really hard to feel for them when they just made (and MAKE) excuse after excuse for the killers' early behaviors that would have been obvious to any normal person that the criminal was trouble and would eventually kill someone. Production - wise, it's also very monotonous to listen to just one person talk for a whole hour. They really need some sort of narration or something to break up that monotony.
