The good parts about this show is that there's a large amount of research, interviews, and very serious and sad cases. All of this is just unwound by the extremely awful and loud music choices to try and make this series more dramatic than it needs to be. The focus really needs to be on the victims; not on the incessant and trashy and even super upbeat music they like playing randomly throughout each of the episodes. Each of and every one of these murders is pretty tragic because it features perpetrators who are just so evil or who are just downright idiotic and sometimes they get the justice they deserve and sometimes they don't. This show really needs to look at better done documentaries and take lessons from them.
