I think it is stupid because it doesn't measure what they claim it measures. It measures their ability to deal with social isolation which has no bearing on MMA. I like the idea of the show, of seeing the training, the general format. The only thing that really bothers me are some of the rules of the house.
It allows them to see how people can handle pressure. I don't see how you can argue that.
If they think that 6 weeks in a house is too much, then they aren't ready to be in the spotlight 24/7.
What rules would you allow? Books, TV, Leaving to go out when ever you feel like it? Wow, that would be a great TV show to watch.
