I think the "don't like it ? then don't watch it" comments are sometimes taken in the wrong context, yes if it's not your type of thing then fine but a large part of peoples gripe is that what was a very good car related entertainment show is getting worse and they're disappointed as there's nothing else of it's type around. It would be good if they could just come up with some different concepts though, clearly some of the people behind the show are very clever so shouldn't be to hard, I sometimes get the impression the show revolves around the 3 of them just dicking about and no doubt getting paid a vast amount of license payers money for the pleasure.
I still like it and still watch it or record it, I feel it's got very predictable, far fetched and I have noticed that when watching live I tend to drift off or if it's recorded fast forward quite a bit because you know it's going to be poor.
Not sure what the viewing figures are but they must be good or the beeb would bin it so from their point of view "if it's not broken, don't fix it"
