"Alesha, 31, was slated by viewers for being too nice and failing to criticise any of the acts."
Where do they get such rubbish. She was slated because she is no way qualifed to be a judge but I don't remember anyone saying she was 'too nice' . The reason she can't do an in depth critique like the other 3 is because she can't. Len, Bruno and Craig have spent a lifetime in the dance world and are used to spotting any mistakes. It takes lots of experience to be able to spot every little mistake. Alesha's world is singing.
Where do the BBC get this mantra that the public only want nastiness from the judges. All the public want is fair, knowlegeble critiques like those given by Karen Hardy.
