So I finally managed to watch Parts Unknown season five finale on Beirut (via torrent download) and was quite disappointed.
The show is actually about food and travel, so I was expecting Bourdain to explore some of Beirut’s hidden gems but instead he went to Burj Al Barajneh refugee camp in the first part of the episode to learn more about the Palestinians living conditions here in the country. He then made several people speak about religious diversity and how the different sects coexist happily in Lebanon (especially Sunni and Shia these days!), and he later visited some Hezbollah supporter in Dahieh all while portraying the party as a mighty beast.
Moreover, he never failed during the episode to stress about the threat coming from the east, that is the Islamic state. So it was basically more about politics than anything else. I believe he could have simply aired some recent report about the political situation in Lebanon and spared himself a trip here.
