Yeah, I agree about the models--but I guess from a producers point of view, you want at least some "beautiful people". And the rest of us do like to see "beautiful people covered with mud or with their hair messed up--and didn't the model couple skip a fast foward because they didn't want to cut their precious hair? If memory serves, that may (MAY! Tough to know for sure!) have made a difference in the end.
We're definitely psyched for this in our house--I'll be taping, though, since I go to bed early--plus, the kids just love it.
