Watched the first episode. I didn't love it, but I sure didn't hate it.
Biggest complaint is the casting -- not a whole lot of likable people, in my opinion. Interesting to see teams composed of complete strangers rather than people who already know each other in real life, though.
In terms of recent summer TAR-type stopgap shows, I'd say The Great Escape > Expedition Impossible > Take the Money and Run > 72 Hours.
