Yes. I won't be specific about who but the response was that everyone seemed friendly but sort of fake and that the meeting material seemed very basic and they were surprised that all the answers (well most of them) were directly from the material or a very minor paraphrase of the material. All in all the person said it had the feel of a high control group (forget what term they used exactly but it wasn't cult). The individual never went back.
This was from someone my wife and I both know and that she took the the meeting one time. I don't know if the individual gave my wife the same feedback I got.
