The Grand Tour was unveiled with great fanfare and I found much of it very enjoyable, but unfortunately, the longer it goes on the more puerile and downright silly it's become. We know it's never really been about the cars, but now the cars are almost forgotten, having been replaced by the lads' egos. Season 4 on boats in Cambodia is cringeworthy and I'll have to pinch myself to watch it all the way through. Maybe the chemistry has gone from the trio because it's just not fun anymore....
