Entertainment QotD: Reality TV Gone Too Far?

"Celebrity Rehab with Dr. Drew" shows the real-life drama of celebrities in drug rehab. Do you think this is helpful or exploitative? 

I LOVE the trashy-ness of this show.  It fills a nice void that's been missing in "bad-reality TV world" since Temptation Island ended.  I think this show would be considered exploitative IF it was a show about non-celebs going through the recovery process.  All of these people are accustomed to being in front of the camera and three or four of them have already been on other VH1 Celeb-reality TV shows (two on the Surreal Life and one on Celebrity Fit Club).  Drugged up or not, they (and/or their agents that got them on the show) knew what they were getting into. 

Is it helpful?  Probably not.  But who cares?  It's trashy reality TV about washed-up entertainers trying to make some money and in the meantime, kick their bad habits.... interestingly, it's already been leaked that one of the people on the show (the blond girl who was on American Idol) has already gotten arrested for public drunkness and being biligerent/abusive to cops since the show wrapped up.  Dr. Drew was able to convince the judge not to throw her in jail.  Instead, she's having another dose of rehab - this time without the cameras....
