I found the documentary a bit disjointed. though it was important to underline the issues that don't get reported in the press, or some holiday makers are not aware of, it could have been a bit more balanced.
Careless words can have an effect...for example York floods were not as drastic as shown in the news, but as soon as our councillors say stay away, that's what people are doing yet the city is open for business, business it needs desperately. Tourism is a big part of the Greek economy,like Yorks, and I know not everyone will do research and some people do believe what they read and take it literally.
However, some of the places the guy visited looked spectacular, I wouldn't mind seeing some of it for myself.
