Imogen West-Knights Slate Feb 11
The film is an interesting and uncomfortable document of whose privacy is deemed important in a case like this. Go to Full Review
Wendy Ide Observer (UK) Feb 10
With no new revelations pertaining to the case, the main talking point from this documentary looks likely to be the footage of the arrests. Bar the noise and the rubbernecking, there is little of real substance to add about the harrowing case. Go to Full Review
Ben Dowell The Times (UK) Feb 7
3/5
This film had all the excellent footage (including police interviews) and the exclusive sit-downs you might want. Go to Full Review
Stephen Silver The SS Ben Hecht Mar 6
The film feels the need to use bizarre AI tech to recreate witness interviews, which just looks silly. Go to Full Review
Carla Hay Culture Mix Feb 11
It does a fairly adequate job of presenting both sides of whether or not convicted child murderer Lucy Letby is guilty of the crimes that sent her to prison for life. Previously unreleased police footage is the main reason to watch. Go to Full Review
Barbara Shulgasser Common Sense Media Feb 10
2/5
Given the use of AI to "create" characters making assertions about Lucy and the case, this feels like an exercise in hoodwinking. Go to Full Review

dzrab M. @RT52294589 3d Hate that they used AI in this doc See more Gabriella S @GatoGato1920 Mar 6 I’m disgusted by the fact that Netflix would use AI when telling such a heart breaking story. Let alone using terribly done AI. I hope the director, writer, producer, everyone involved are ashamed of themselves. I hope this story gets told in a manner that’s not so disrespectful to the families of the victims. See more Meghan T @RT56415614 Mar 4 While the subject of the documentary is compelling, Netflix does an awful job with the delivery (which isn't much of a surprise.) Shame on Netflix for using weird AI people to replace human actors. It definitely takes you out of the narrative. I will now research what I watch on Netflix before I watch it so that I can avoid the AI slop. See more Abena A @Abena814 Feb 22 Another show trying to plead for a murderer. The friend is sickening how she tries to justify this. Explain how she goes from one shift to another and the deaths follow her. Sickening how they put out these movies to try to make you feel empathy for the killer over the victims. Those poor defenseless babies. The lawyer and the author should be ashamed of themselves See more Robin H @RT16578982 Feb 18 An interesting coverage of this extraordinary case. However the whole affair acquired an air of fantasy when everyone started to question the compelling evidence. There was a Chinese so-called expert, Mr Shoo Lee, who came along years later, claiming that he and his associates had decided that in EVERY ONE of the seventeen cases the official diagnosis of death was wrong . There were people brushing aside the concrete evidence that there were NO BABY DEATHS amongst the several hundred births both before and after the presence of Lucy Letby as the nurse in charge. There was no psychological evidence to explain why the clear confessions in her diaries should have been the result of disturbed fantasising as claimed. Why anyone should be bothering to sabotage such a clear cut case is bewildering, and the program should have investigated that. Oh, and the accompanying menacing sound track was both distracting and utterly inappropriate. Why do directors do that? See more Aye E @RT43717499 Feb 15 Not only was the topic disturbing but it's barely watchable each time the AI interviewees come on the screen making inhuman micro-expressions. Just made me uncomfortable and queasy. There are so many other ways it could've been done if they didn't want to be identifiable. Even if they had actors portraying them it would've sounded more authentic and actually emotional then it did with these AI renderings. Or put the subjects in shadow behind a screen with wigs and hats on, it's worked fine before!!! See more Read all reviews
