I really enjoyed this show.  My only complaint was the solution to the next-to-last puzzle, when the CIA group honestly (and understandably) thought they had won. 

IMHO, they should have had some way of avoiding ANY confusion about whether or not one was eliminated.   (If they couldn't copy TAR's finish line, they could at least have had something which would have told the groups whether or not they had succeeded.)
