I'm never against anything that helps...
with that caviat in mind, I've worked in the alcohol and drug treatment industry in the past and will tell you that the problem I have with RR is that it isn't necessarily an abstinence program which flies in the face of the dis-ease model of addiction (the biochemical/genetic/psychological/emotional/social/cultural/spiritual dysfunction model) that says one is too many and a 1000 is not enough.
However, that doesn't mean it can't or won't work. It is just not something I would ever recommend to anyone.
I also don't know it all. As a professional who worked with alcoholics and drug addicts I would have felt I was committing malpractice to have recommended it. I'm sure I couldn't have been sued for that as even 12 step programs have low success rates and it would be hard to argue that there was truly a terrible risk by not recommending a 12 step program.
I sobered up in AA, and have found recovery there. I'm biased, and I know it!
If RR works for you d00d, then I say more power to ya!
