I found this documentary horrible and I don't know how it managed to be the most viewed in the UK, probably because of the expectations we all had.
Starting with the fact that the episodes are about an hour and a half long, so there is plenty of margin to talk about the victims as well as his working life.
I thought this documentary would expose a lot of crimes that were buried for a long time and then came to light, but the victims were only shown in the last 20 minutes of the second episode. So I wondered what I watched it for. Even when the victims were talking, right after there was him talking about something random. Really this documentary felt to me like glorifying a pedophile.
