I probably did take it a bit too much as fact, as it was the only insight I had into that era. I was somewhat skeptical just because he also said Robin Strasser was a bad actress, - to me, while Strasser can be very hammy and one-note, she's also capable of superb performances.
When I actually saw the brief clips of Courtney available (for a long time the one I most remembered was the "smile" one when Steve went to prison, which was a bit cheesy), it did change my opinion - I think what most changed it was when I got to see the material around the time she was having a breakdown and attacked Rachel after Rachel visited to taunt her. Lemay had gone on about how bad she was and he had to cut the story short because she was incapable. Her work there to me was very strong, and she also seemed much tougher as an actress to me than I'd expected, as Lemay depicted her as a crying ingenue.
