A lot of people do find the twins entertaining .. they aren't everyone's cuppa tea but then who is ?
Louis gave his opinion on Jamie every week saying that he didn't think he was a good singer .. not everyone agrees but it is his opinion.
Cheryl wasn't slated for saying she doesn't "get" Danyl .. she has used the word 'cocky' every single week when talking about him and that's what's earning her the 'nasty' label. She should've followed the other two judges and dropped it after the first week .. especially as Danyl has radically changed his performance technique in order to avoid that label.
I wouldn't class Ricky as big band but I think this whole "rule book" thing is just a standing joke now
