I really liked Orange County Choppers for about two seasons. After that, they jumped the shark for me. It was the same damn thing every week and I finally realized that the bikes basically suck and are probably unrideable.
Same thing with the Storage Wars guys. I liked Barry and Brandi and always hoped they'd find something really good. After awhile, though, it just got real boring and stupid.
I rarely watch television so it's tough when the 1 or 2 shows you watch turn out bad. Right now, my favorite show is Duck Dynasty and I was very disappointed in Jase's performance before the HMO board. He acted like a total pussy. One more show like that and I'm back to making up my own programs in my head.
