My experience has been the opposite, with multiple therapists. No one ever made pronouncements about my effort one way or the other or commented about the correctness of my therapy work. When I said I needed things done differently, they did them. When I criticized them, they listened openly and were straight with me about how they saw things. When there were big screw ups, and there have been a few with each of them, some that I still can recall, they acknowledged what they could have done differently. No one ever pointed a finger at me or said something was my fault. Fault didn't ever enter into it. I'm much more interested in understanding and resolution rather than being proclaimed without fault. But I would leave therapy if I felt blamed or that I couldn't say what I needed because of repeated defensiveness (sometimes people are defensive at first, especially if they feel attacked, so the process is often not perfect), but I couldn't tolerate being stuck in this way. Bad therapy is bad therapy, but therapy isn't always bad.
