I wonder if some are disappointed with Louise because of how she was and seemed to deport herself in her younger years. The Louise from the glam shots and Eternal does not have the same image as the Louise on Strictly. Of course times change, she's older and worries what her children will think. Unfortunately I think Kevin may contribute a bit to her tweeness, vanilla-beige, wet hen image.
One thing I respect about Louise and that may contribute to her reserve and follows from her goodbye words about Daisy, is that she knows what the 'industry' is like and wishes to protect herself and her family given the industry and its disingenuous ways. A good many of us on this forum are cynical about producer manipulation of the show. For someone inside it, who may have been burnt by it in the past, she wants to ensure this does not happen again.
