As for the show, interesting. Basically they put a group of people together, from what I gathered in the show I watched, in a post-apocalyptic world. Then they let the "fun" begin. I'm not sure how "realistic" it is, with all the camera crews, etc. but from what I saw, it looks like only a couple people really know what to do.
Like I said, it was only one show. Will I watch it again? Maybe. Will I schedule it on my DVR? Nope. It didn't really grab me, except maybe that Gatorade drink.
Now that looked interesting.
