Some quick thoughts:
We may have found the dumbest pair of reality show contestants ever. Erwin and Godwin are lucky not to have been arrested for using water pistols in an airport.
A number of teams got bitten for not paying attention when laying the bricks when they didn’t notice the pattern used large grey bricks as its border but it was the last team to reach that detour than got eliminated.
I wonder what was the correct method using the climbing rope’s loops. Since the show focused on the people having trouble the viewers really could not tell how hard the task was.
Finally on the show’s website the producers should provide the exact times at which each time reached each clue marker, detour, airport, taxi, etc. The people who just watch the show won’t care but many would love to how those details.
