I find it quite interesting and have been following it for the past four weeks. It is an American Reality show and there will be only one winner for $250,000. However, although the Japanese Game Show is purely fictional it is played and acted out as a real Japanese game show complete with the MC, audience, behind the scenes personnel, etc and also complete with the most absurd and humiliating types of Japanese games as one often sees when in Japan.
It really gives the uninitiated an excellent look into Japanese game shows, but in the American version the losing team has to plant rice, shuck clams, etc and the winning team gets to go to spas, and enjoy the good life in Japan.
The only thing I don't like about it is that it is your typical American reality/game show where there is only one winner and eventually everyone tries to put down or out do the others including their own teammate and there is much backstabbing. However, since it is related to Japan, filmed in Japan, and shows a little of real Japanese culture I will continue watching it. It is funny and watchable and does have it's finer points. I would recommend it, but that is just my opinion. It is not as cliche ridden as I thought it would be. As a matter of fact it was done quite well.
