Love these guys. I can't wait for it to be released, hopefully seeing some improvements over season 1.
Yep, all they really need to do is go off script more and drop celebrity brain crash. Jeremy, James, and Richard have proven time and again that they're at their funniest when they aren't scripted and are free to just be themselves, that's why the Top Gear Christmas Specials were so popular, they were just the 3 of them exploring a region of the world on a multi-day road trip, being themselves. As for Celebrity Brain Crash, it was a clever way for them to poke fun at the BBC's legal team for trying to block The Grand Tour from having celebrity guests, but it got old pretty quickly, best to drop it now.
The trailer is promising, the dialogue sounds like it isn't as heavily scripted as the first season was.
