I didn't watch but for me therapy fell a little flat because the therapist was so assuring me that I was a good person in various capacities. This stranger who only had my side of the story was asserting that I was doing the right things and should feel good about them. I couldn't find such an opinion credible, and felt like all they were doing were things I could say to myself but even less credible than me. External reassurances from a stranger trying to override my self doubt just kind of backfired.
It probably works for other kinds of issues, but didn't really do much for me.
