Arlene's comparison of Lisa and Christine was entirely unnecessary and unprofessional (the comparison had already been made in the scores - why say anything more?)
The implication that Christine wasn't working on her dancing was, quite simply, unforgivable. It was not only quite patently false, but also a huge insult to Matthew's professionalism as her teacher and Christine's professionalism as a television performer.
I seem to recall Arlene making similar comments about Alesha's footwork last year. She has only become worse in the interim. Her 'advice' is lazy, her critique increasingly biased. Unlike the other judges, who I have all disagreed with at one point or another, I can see no redeeming features in her any more. I don't know who I will support now that Christine and Matthew are out, but I do know that I will no longer be listening to Arlene at all!
Sorry, rant over! But oh, I needed to get that off my chest!
