I have vivid memories of this feature-length documentary when it was broadcast on Channel 4 (UK) sometime in the early 00s; I must've been between the ages of 10-12. And it certainly made an impression.
I've classed this a first-time watch as I cannot remember if I watched the entire film at that point in time. Disturbing, interesting, powerful and, at times, frustrating - a must-see but I understand the off-putting nature of how it was made, which you can see opinions of in other reviews. Grace Quek (a.k.a Annabel Chong) is a fascinating lady, intelligent and her personality keeps the viewer's attention.
