I liked it. The pacing was a little slow, but It's more focused on the police work involved in catching the killers & the victims rather than the killers themselves which i think is a nice change from the majority of these types of shows which more often than not seem to glorify the monsters instead. As for the episodes themselves, i think they showcase good police work in the first 2 episodes where you can see just how hard the detectives involved worked & are still traumatically effected by everything they had to go through to get the person responsible vs. Bad police work in the last 2 where you keep asking yourself how they all still had/have jobs after they botched the case so bad & still take no responsibility for any of the many obvious mistakes they made.
