Yes, although she seems compassionate & caring, she comes across a bit condescending and she's always looking for a negative angle, but seems genuinely surprised when there are positives...but at least they make it to the final edit and don't hit the cutting room floor....so fair play to her and the producers for allowing a balanced view.
I'm not sure I entirely agree with that, IMO it's all about making good TV with a generous dose of "real" emotions of both the filmed subjects and of Stacey herself.
Call me a cynic but I find all this as "real time emotions" hunt is part of the dumbing down of modern TV, in reality a lot of it is staged or at least cleverly extracted.
