I quit watching a few reality shows because they seemed too scripted. Lest I mention someone's favorite show, I'll only tell about the ones I like. Most of them are on the History Channel  

I like watching the Picker guys climb over junk and finding things I grew up with. I also like their personalities.

I find the Pawn Shop show interesting, watching them wheel and deal and seeing what people bring in. Their personalities also perk my interest.

Swamp People excites me when they are catching an allegaitor. It's hard to fake the catch. If I were there, that allegaiter would pull me in the water and eat me, I just know it. 

House Hunters on HGTV may not be considered a reality show, but I enjoy watching people spend triple the sum of our house payment on a home I wouldn't want to live in -- and I'm not picky. Those houses are in large cities.
