I've been actively watching this show for a few years now. There is no other show that even comes close (in this genre). I really hope this series gets 'big' and well-known. Justin and Scott are just a great match on screen, and a great traveling duo (along with their cameraman, Andre).
What really sets this show apart from other shows is the cinematography. Andre has a gift. Of course he has a nice camera, but the shots are so well-exposed and composed. I think the 'look' of a show is very important; I'm not sure what other productions are doing or using, but Andre is doing it right.
When you watch this show, you always feels as though you're with friends. If you want to travel, but don't have the means, this show is perfect. Personally, I would prefer if they went to more well-known areas... as that is equally interesting for me; I found the Japan trip to be one of the best episodes.
As well, I have to mention North Korea. This episode is educating... throw out everything you already know about this country.
Also it should be mentioned that their editing is really great too. The small and clean logos and animation work is quite good and well defined. Editing and synchronization with the music really sets the right mood.
To conclude, the photography/cinematography is well-above most television shows, and the content is extremely engaging. The most important thing though, is that when you watch this show, you feel a certain familiarity and begin to latch onto the characters.
I wish this show was on more often!
