Lucy Mangan Guardian May 4
4/5
More shocking than the police neglect and stupidity is the lack of comprehension that David Green, head of homicide and major crime, Scotland 2019-23 appears to exhibit towards the woman who handed them the case on a platter. Go to Full Review

While it feels like there's some information left out, the documentary still satisfies that true crime itch. [Full review in Spanish] Go to Full Review
Carla Hay Culture Mix May 16
Should I Marry a Murderer?--although not as comprehensive as the BBC docuseries Murder Case: The Vanishing Cyclist--sufficiently presents a narrative from Caroline Muirhead, who was engaged to a killer and was a key witness in this homicide case. Go to Full Review

Avindu G @RT86379654 2d Should someone wonder if they can start a new life with someone who has taken another man's life? The answer that Caroline's collision course towards justice would give may raise all the brows existing and none. When what's right gets buried in bureaucracy and an ingenious scheme of getting away with murder, the only hope of this story becomes the closure and a dignified resting place for the dead. Breaking all norms of conventional true crime docs this three-parter explores a unique angle and a truly mysterious set of events surrounding a tragedy.

What a narcissist. See more Adam R @RT16485074 Jul 1 I find it sad that this has so many poor reviews. You should not see this as a doc about a psychopath killer it’s more about how your life can fall apart if you trust the wrong person and get involved in drugs and drink and the damage this can cause. By the end you can see the impact of poor decisions and trusting the wrong person and the huge impact this can have on your psyche and life as a whole. It’s also a great story of how the police can badly fumble a vulnerable person to the point where they are in serious danger. It’s a bruising tale of a life that falls apart the seams but if you want shocks and gruesome murders this won’t be for you. See more John V @RT67154737 Jul 1 This is one of the worst documentaries ever made. This was a 30 minute story dragged out into 3 episodes. There is something deeply wrong with Caroline. She takes video of herself alone constantly and rambles on like a mental patient. We hung on to see if there was some amazing ending, but there was not. Don't bother.
