Just to play Devil's advocate a minute, I assumed the booing was at the public's decision rather than at Johnson himself. They were expressing their dissastisfaction with the result rather than any particular dislike of Johnson,
Having said that, I don't like booing in general. It's not very sporting and it lowers the tone. In fact I never liked it in Big Brother either
I can understand why people would want to vote for Johnson but, personally, I think that when you have a competition like this one it is inherently unfair to the other competitors if a person's ability at what the competition is supposed to be about is not the primary factor in deciding how well they do.
It's human nature to be swayed by other factors but it's not objective and, as such, in my opinion, I don't think it's fair.
Having said that, with the exception of Jennifer, I don't think we've lost anyone we shouldn't have because of Johnson but I would definitely not want to see him getting into the semi-final or final. That, in my opinion, would make a mockery of the show's basic premise.
