There are so many docs and TV shows I have yet to watch so I never watch that crap.
The closest to "reality" TV would be Food Network shows. My wife watches way more than I, but I do like Tournament of Champions, Guys Grocery Games and 24 in 24. I typically try to visit the places that those chefs run if I'm in their town. Same with any of the travel shows for food, like Diners, Drive-Ins & Dives.
But things like Top Chef where it's basically Real World with cooking or anything Gordan Ramsey? Nah.
Watching Mad Men right now with the wife and The Americans after she goes to bed.
