Like most other shows on Investigation Discovery, this one draws you in right from the start. It's a real life "who done it?" Some of the cases, I never would've expected that the killer was the person it was, but others were somewhat obvious based on the narrative, however this show is definitely worth watching. It's also a reminder that even decades later, cases can still be solved and often are thanks to new technology and information.
I've literally binge-watched every season of this and I'm looking forward to another one because like most other true crime junkies out there, knowing that these are real stories are precisely what draw me in and get addicted to the show.
