The problem with threads like these is not the destinations themselves, rather the expectations of the visitor.
New Zealand being meh - is just about the most ridiculous thing I have ever heard. It is the most awe inspiringly beautiful place I have ever visited. Seriously - if you didn't find the South Island spectacular, this says more about the visitor than the destination.
Other places are not like England, for sure but that's the beauty of travel. The middle eastern ones are a good example - some may see dirt, chaos, begging - yes there are those things. There are other things though, history, culture, architecture, food, allure of something different.
The AI and package holiday has a lot to answer for.
