I find a lot of the crew annoying, but I hardly ever look at the screen, so I can tune them out.
Tom's incessant blather is kind of like white noise (unless I notice something kinda dumb he says, like "do as many as you can...even if it's just one or two" : um..if someone can only do 1-2 of a move, they proably aren't ready for this series!).
I like his voice, and it's more just part of the background for me. Now, if it were someone with a horrible voice, like Denise AUstin (IMO), it would drive me bonkers.
