The level of access for the cameras is impressive. You see everything but the dead body, which elevates this show above many true crime shows relying on recreations. The pacing is good, the police were very professional and respectful, and the show provides some insight into a murder investigation.
Unfortunately, the show comes up short in the entertainment department. There is some suspense as to when and how they will fund their suspects, but ultimately there is no mystery here. The second crime was even caught on video, which was pretty digsusting to watch. A couple of the interrogations were interesting, but too much time was spent on the "No comment," interrogations.
Again, if you want realism then this is the show for you. If you want drama, mystery, and intrigue then you might have to find a fictional show or a true crime show such as Murder Board that focuses on narrowing down suspects.
