We rented this movie thinking it would be more of a travel movie about Greece, with some commentary & comedy thrown in. Instead, it's a lengthy dialogue between two guys who THINK they are very clever, but who just come across as insufferably pompous. The fact that the dialogue takes place in Greece is almost beside the point, as they could be eating lunch, or driving in a car, almost anywhere. There is very little attempt to actually show us Greece.
It may be due to the fact that, as an American, I don't already know these two guys, and sometimes my sense of humor doesn't quite align with the British sense. The show reminds me a bit of Jerry Seinfeld's "Comedians in Cars Getting Coffee", except that Jerry and his guests are aware that they are basically full of baloney, while these two actually seem to take themselves seriously. We turned it off after 40 minutes, wishing we hadn't wasted the money.
