There is essentially nothing here that is inappropriate for children in any way, shape, or form. The only issue that you could possibly raise is profanity. But it is very mild, and rather infrequent. Seriously, Regular Show has more profanity than this show. But anyway, this show has plenty of positive messages. Like you said, the only way to win here is through teamwork. But you ignored the implication that that also means that any team that DOESN'T get along in this competition at any given point fails. Also, you have to keep in mind that, aside from the U-Turns, there's aren't any attempts to get rid of another player. Instead, they are all simply trying to finish the tasks as fast as possible. Therefore, this show is VERY good for family audiences because children will take in all the various cultures presented here that the teams visit, and of course, the underlying message of teamwork. Unlike Survivor and Big Brother, girls aren't seen in bikinis, contestants don't try to backstab each other, and there are no sexual innuendos. So if you really have game shows so badly as to make the grossly innacurate rating that you presented to this show, then you should probably rerate Wheel of Fortune iffy for ages 10-12.
