I just watched it on Tivo with my wife. A lot of that sounds very familiar. Oprah did do a good job with this one.
Just finished streaming it. Very powerful, and Oprah managed to rein herself in to a degree, and give a public service by having the whole family's input and giving a plug for RAINN at the end.
Gregg Mulligan himself was also articulate enough not to have too many words put down his mouth by Oprah so it was a very balanced interview because she didn't get away with her usual "didn't you enjoy it" bullshit and rephrased "how did it feel" as "tell us what it did to you". Hopefully it'll get parcelled into 4 parts on Youtube so can be seen long after it goes off her site for the sections that were helpful.
On reflection, if it wasn't such a rounded packaged story IE his mother is dead, he moved on to marry and have a child that grew up fine - you'd wonder if that programme would have turned out as above-average as it was compared to her siding with female offenders in the past.
