The premiere of The Grand Tour was a big event, and initially, I thought it was quite good; however, as time passes, it’s devolved into something immature and frankly ridiculous. It’s always been clear that the show wasn’t primarily about the vehicles, but now they've faded into the background, overshadowed by the personalities of the hosts. Season 4, with its boating adventure in Cambodia, is hard to watch and requires a conscious effort on my part to get through. Perhaps the dynamic between the three presenters has deteriorated because it’s simply not entertaining anymore.
