We all love to see places that seem alien and completely bereft of modernity. The lush mountains, the historic villages that seemingly have no electricity or running water and just the rustic appeal of the supposed third world. Every now and then we have that little itch to explore these places, and that is where the film The Loneliest Planet excels in. Other than that, it doesn't excel at much else.
I guess the problem comes from the trailer, which made this sound like a major issue was going to form between the protagonists Alex and Nica. They seem very much in love and quite comfortable, but it is revealed late in the movie they may have some trust issues. While this is typical of these type of movies where stresses create relationship cracks, it wasn't anything too earth rattling. Even the major moment where the marital bliss is challenged doesn't illustrate this. Another reviewer on this page suggested this would have been a better short film. I would have to agree.
I will say the scenery of the Caucasus Mountains is extraordinary, making me wish I had the means to go out there and experience it for myself. Other than that, a well shot and composed film with little else to really offer.
