I only watched last 10 minutes so obviously missed a big chunk... It appeared the children in the program behaviour really needed parents to change.
I am not judging all parents by this standard ( or even these as I missed so much ) but there is peoples parenting that are exacerbating childrens behaviour.
I saw the one guy at the park ..saying we need to do more of this now he has said he liked it ( or something like that ) why would you not anyway?
I would also imagine these programs also have a remit which was never designed to make the parents look good
