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

Sedale S. @sedale143 1d Netflix using snapchat filters for anonymity instead of covering them in no lighting is a freaking wild to unnecessarily waste money. Also, such a boringly made documentary about a serious crime and for it to not be taken seriously is so infuriating. See more Hayley W @hayleymovies 1d This documentary didn’t add much new information to the case of Lucy Letby. I felt the documentary makers tried to even out the damning evidence of her guilt with her friends’ testaments of her good character, but if they were going for suspense, it would have been both stronger for her case and more interesting if they spent more time explaining the defense’s arguments. Hearing her friend talk in circles about how Lucy couldn’t have been guilty was excessive. Also, the use of AI to obfuscate the identity of some of those interviewed was poorly done and really distracting. I could not finish this documentary. See more dzrab M. @RT52294589 Mar 14 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 Read all reviews
