I've watched the show several times. Some of the people featured seem to be real hardcases. I don't like to be judgemental, but I know I would never get to the point that some of these people reach without seeking help. But then again the bottom is different for everyone, so perhaps some people really do need intervention to breakthrough. The interventionists don't really have that good of a reputation in our society, because they apparently do interventions on behaviors that aren't always illegal, like cult-religious, gambling, or other behaviors. But in the case of chemical dependency I believe it's warranted sometimes.
