I don't know the circumstances or logistics behind your being in IOP, but if you have the ability to seek a different group simply say that this one seemed too informal for your needs. The truth is that many people who are court ordered are not terribly interested in recovery, they are simply checking a box they are required to have. Yes, the counselor is not doing a good job, but that's secondary - this isn't a good fit and the odds of getting it rectified to your satisfaction in the near term (which you need for your recovery) are pretty slim.
Move on and get down to the business at hand.
