I must add that I found it interesting that my wife actually enjoyed watching the US version, but she can't stand when I'm watching the UK version (which is pretty frequent... lol)
I second the fact that Jeremy Clarkson makes the UK version, and the fact that May/Hammond are still better than the US guys. The US version is "trying pretty hard" and comes off awkward at times, but it was still very entertaining overall.
I gotta say that I think my favorite UK episodes are the one where I think they're in a jungle (Amazon?) and their cars show up on a boat, and they gotta get themselves outa the jungle. Absolutely awesome episode.
Close in second, was where they had to get from Iraq to Israel in their 3,500 GBP 2-seater sports cars. That was a gooood episode! The challenges and cinematography are incredible!!!! (Hopefully I spelled cinematography correctly....!)
