A difficult but worthy watch and ultimately one that treats Nikki, the illness, and indeed Big Brother with respect. Indeed it's refreshing to have such a documentary not be a beat up of reality TV - her friends and family are unequivocal that it saved her life and after hearing more about the 11 years in childhood she spent in various clinic it does make you see some things differently. Her diary room tantrums for example can be linked to visits to a "screaming tree" when she was in the clinics, and the Big Brother house was somewhere she clearly felt safe - kind of mimiced that institutionalised environment.
From a trivial point of view too C4 always treat archive Big Brother pretty well - and the few well curated clips here really gave me goosebumps. It really was reality TV unfiltered back then and all the better for it, whilst nowadays it feels like so called reality TV hides itself behind a superficial facade.
