Not sure I agree with that article. It's more than likely growing pains. Top Gear was honed over more than 20 seasons.
We're comparing a show in its first season to one that had years to perfect itself. Now, obviously they're not starting from scratch since this essentially is, "Top Gear part 2."
I'd say if the next season still had retarded shit like the American and felt as heavily scripted, maybe it would be an issue of needing more creative direction. But as is, they already filmed all of this. They're not just going to cut last week's challenge (with the eco-vehicles) because that's a massive amount of money they already spent on it and filmed. Likewise, the rest of this season will be filled with terrible segments, because they already shot them all.
Top Gear had a formula that was crafted over a very long period of time. All of those ideas weren't winners, and they culled them. The Grand Tour is suffering a bit from both being a new endeavor, but also trying to capture some of that Top Gear magic while not being Top Gear. It's a tough thing to balance and unfortunately they will have to wait until the next season before they can tinker with it.
I do wonder if they could find something better to do than the celebrity killings and "Conversation Street" on the fly, since those seem to be filmed closer to air time.
That all aside, I think my disappointment from this show has more to do with the fact that I was hoping with a new massive budget and longer shooting time that we're end up with something more akin to the epic specials they had, and less the old Top Gear formula. Instead of dicking around on an 11 mile trek across Britain in some Land Rovers, that we'd maybe get a trip across the Alps, or a challenge in the deserts of Australia. Instead we got an awkward Special Operations parody starring old men and May digging a hole and making bricks.
