Slick production, shoddy narration that not only misrepresents itself as an "investigation" (everything "discovered" seems to have been generated by police work from years past) but also doesn't know how to construct a coherent story (what in the world is this actually about? it starts laser-focused on a particular crime and victim, and then gets so enamored with a rotating cast of killers it goes chasing -- and almost glamorizing -- them instead, almost completely forgetting the original victim). Poorly done.
Sometimes a guilty pleasure is just guilty. This show encapsulates much of what can go so wrong in the true crime genre: valuing little narrative thrills and gimmicks over an actually responsible, clear-eyed analysis and reliance on facts. Tawdry.
