I watched last night. I was very disappointed. Just like all the other "reality" shows on the Discovery/Science channels -- Family members hollering at one another. Nothing technical. All "drama".
Food network is the same. Yelling in the kitchen show. I'm sick of that crap.
American Chopper started that genre-- and I'd love to see it go away. If I want to experience families hollering at one another, I'd turn off the TV.
