I don't know if I'm getting old or what. But just about all I watch nowadays is shows like Mythbusters, Dirty Jobs, No Reservations, etc. Workaholics and the Kroll Show are the only two scripted TV shows I watch (I still like movies though). I'd love to discover more shows like this that I might be missing.
Here are my favorite shows right now:
Dangerou Grounds - the host travels to hot spots around the world looking for unique high-end coffee. Coffee only grows in mountains in the tropics, which happen to be a lot of the poorer, more dangerous places in the world. I like the show because the guy seems pretty genuine, and it's just him and one camera man. So they can get into and out of some tight spots really quick. Also the scenery is amazing.
River Monsters - Huge man-crush on Jeremy Wade. This show never fails to blow me away.
Burger Land - the host travels the country for the best burgers. I like it because his favorite style of burger and mine seem to be the same - greasy meat, cheese and onions all fused together with the bun (like Town Topic - still looking for the equivalent in LA). And he gets into the history of the burgers in the places he goes. I enjoy them vicariously when I'm trying to follow my diet.
Parts Unknown with Anthony Bourdain - I'm a huge Bourdain fanboy.
Alaska State Troopers - for some reason I tend to watch marathons of this when I'm hungover. I guess because it makes me feel good about my situation. There is nothing more depressing than a modern Inuit village.
