I agree with everything you said. I watched the TGUK episode on Monday night and was severely disappointed. The jokes mostly fell flat, there was almost no information about any of the cars, and they didn't even tell us how they drive.All in all, this was a great deal more fun than anything TGUK's done over the past two weeks. You can't do better than junkers, rifles, pyro, dropping cars from cranes, and a dirt obstacle course. Plus, no one can claim that this is a direct rip-off of something TGUK did, and considering that TGUK directly ripped off TGUS this week, that again makes this episode superior.
I'm giving it an 8 in order to counter-balance the intense over-rating that's occurred in the TGUK threads for those two sad-ass excuses for Top Gear.
