Review of Chris Tarrant: Extreme Railways

I am very bemused by the reviews that describe Tarrant as respectful to the citizens of the countries that he visits. Tarrant is a firm believer of the 'speak loudly and slowly while gesticulating' method of communication with those who don't speak English. Rather than bother to learn a few crucial phrases in the language of the country, he just gets frustrated by the locals inability to understand him. 'Looks like she's in the wrong job' was a classic comment from him when a train guard couldn't understand his question. Why do we insist on sending embarrassing, rude people to produce shows that could be so much better and more educational?
