I actually liked Dual Survival. Sure, there was some odd and questionable stuff in there, but I found it entertaining none-the-less. Lots of times I found myself thinking, what would I do in such a situation? (no matter how contrived for TV the situation was)
I liked Cody and Dave, I was worried when Dave left and Joe came on, but that turned out to be OK because I liked Cody and Joe too. I'm not sure what the show will be like without Cody however, if it even continues. I could identify with Cody's way of thinking the most (except for that barefoot thing).
