I think it's kind of like Rate My Professors—the people who write the reviews are going to be the ones with an axe to grind, and their reasons might or might not be good. Some people think therapy is like magic, you go ten times and bang you're cured, and they get mad when that's not true. Like I used to have a friend with a heroin addiction who could never stick with a therapist, always said he was too smart for them, whatever. Truth was he just lied to them about his efforts to quit using. He thought that didn't matter, if they were good therapists they should be able to cure him anyway.

Plus there is so much talk about the "fit" between the therapist and client. I can imagine a lot of clients giving negative reviews to therapists who just weren't the right fit for them, for reasons beyond anyone's control.

All that said, if the same issue is mentioned by several people, there is a good chance it exists.
