The documentary takes a detailed look at the disappearance of 3-year-old Madeleine McCann, who vanished while on holiday with her family.
"Interesting story. Glad to become more familiar with the history. Certainly no need to drag it over 8 episodes. Very slow and repetitive at times."
"It's intriguing at first but it just drags on through every episode. Could've been maybe two or three and it would've been fine"
