I forgot to comment on the programme - I think Coogan did an excellent job. It was very disturbing, but I do feel that dramatisations of things like this are important. As people have said, younger generations won't know about him, and it is important that all of us understand what can happen if people don't speak up. I also think it's important that those in authority know that they will be called to account if they don't protect people - if there isn't enough evidence they should do more to find it, and listen to those who report abuse rather than demanding proof which is often impossible to provide.
I'm not sure about the psychology aspect - the implication that Savile's crimes were a result of his mother's relationship with him. It's possible, and I believe the research for the programme was meticulous, but I'd have liked to know more about how that conclusion was reached. There was mention at the start of how his mother used to beat him as a child - probably not uncommon in the 20s and 30s, but I can see how that could lead to a belief that children and young people have no say over what happens to their bodies. That wasn't really explored though, and I take Caravansera's point that blaming a woman for a man's crimes is depressingly common.
Otherwise, I think it was very well done.
