Vicky Jessop London Evening Standard 2d
1/5
This should not exist. It is simply picking over long-clean bones for bad reasons: poking a terrible bruise for the pleasure of onlookers. Go to Full Review Lucy Mangan Guardian 2d
3/5
The Investigation of Lucy Letby does not compare in its attention to detail, preferring a broader-brush, more emotive telling of the story. Go to Full Review Sarah Knapton Daily Telegraph (UK) 2d
3/5
...it suffers from the current irritating documentary trend of having contributors talking in the present tense about past events. But it does give a fascinating insight into the police investigation and their treatment of their chief suspect. Go to Full Review Karina Adelgaard Heaven of Horror 2d
3/5
... watching a Netflix true crime documentary like this is tough. It’s about the untimely and shocking deaths of many newborn babies, which IS a hard watch. And it is so very easy to get angry at Lucy Letby for not reacting as you may... Go to Full Review Read all reviews

Ry C @R.cliff 43m Genuinely awful that someone thought AI was the best alternative here. Completely unwatchable . Completely Biased editing. Save yourself 90 minutes and watch something else . See more Jack T @Jacktomo22 1h AI slop. As soon as it appears on the screen all credibility goes out the window, can’t even be arsed to have an actor voiceover at least. Just disingenuous to an awful situation. See more Megan B @Me3gan 13h The AI sequences are so weird and ugly and it’s distracting. Just hire an actor to read the testimony or hide the person behind shadow. Terrible See more Kristen B. @SagiTurq 1d This documentary utilized AI to recreate humans in emotional interviews. It’s distracting and disturbing that we’re allowing AI into film. I turned it off as soon as I saw this first AI impersonation. See more Caroline L @Koala171 1d Should get zero stars. This is not filmmaking. AI slop. Such a serious topic, to use AI characters is unforgivable. Use actors. Made it unwatchable. See more Benjamin E @Benjamin97 1d Genuinely one of the worst uses of Ai slop I've ever seen. Lazy documentary makers. I felt detached immediately. Turned off after 10 minutes.
