I wouldn't say I'm happier with TGUS over TGUK. They're different experiences.
I discovered TG when a friend sent me the clip of the Reliant Robin Space Shuttle on Youtube. I thought it was pretty good and read about the show online. At about the same time, BBC America played a marathon of Top Gear, so I got to watch several episodes. After that I realized I wanted more of that, so Pirate Bay helped me with that. I enjoy many things about the show, the fast cars (many of which never seem to cross over here to America), the challenges, the epic-length films like Botswana, but most especially I enjoy the three guys screwing around and being car guys. So they bash America, Americans and American cars, so what? Every car person I know has favorites and stuff they don't like just on general principles (Ford vs Chevy anyone?).
But I like TGUS too. I liked the first episode race between the Viper and the Cobra; what town in England would let that happen on their streets? The parts that were most like TGUK were the disappointing ones, because I'd seen that already and it didn't really fit the theme of the show, which was three competitive friends having fun with cars (TGUK on the other hand is obviously three guys who don't care much for each other and one of them is clearly dominant over the others - Clarkson). Other things from season one impressed me too, such as the used car salesman idea; it was brilliant! And the truck challenge in Alaska really went to the heart of American car culture with its Ford vs Chevy vs Dodge theme (and all of them shunning the Toyota).
So, yeah, if TGUS was just supposed to be a clone of TGUK, then it is obviously broken. But its not a clone. Its an American car show with the Top Gear brand name attached and I think its doing a pretty damn good job. Its light years better than TGUK was at the same time in its lifespan.
