I've always quite liked James but he does seem to have been dragged up. His parents don't appear to have instilled basic good manners into him.

Some posters have said they worry about FMs who complain about his manners, but I think they should worry elsewhere. This is a family show, and I think it is a bad example to young people watching. Sorry if that doesn't suit, but I feel strongly it should be said.
It shouldn't be necessary to explain that they are all good friends really and all of that. People can understand that perfectly well, and still object at the same time.
Jason took it in good part, but he would have to anyway. I think he was a little unsure about it myself. As for Brendan, he is usually a gentleman, but when he's behind Tess with James his behaviour deteriorates. Very schoolboy behaviour and they are no longer schoolboys.
I fail to see how gibbering like monkeys behind the other contestants is funny, and maybe it's true they are egged on to behave like this, who knows? Good job the producer is going if that is the case.
James is losing the support he had from me and no doubt others if he carries on like this. As other posters have said, some of the other pros seemed to think his behaviour was OTT, and whether this is the case or not, they should have done.
