A reality show without girlish drama is a reality show that is destined to be a failure that gets cancelled. Its common sense. Thats why the drunken drama is shown.
Your right, all those other sports did have a strong huge following. And thats something that this reality show will help MMA create. Its only going to introduce more people to the sport. That is good for the long term because long after the show is over the fans brought in who like the sport will stay fans.
Maybe. But maybe not.
Maybe the people they are attracting through this tactic just want to see blood, or drunk tough guys brawling. Or maybe all they care about is the girlish drama and a TV show.
Maybe they are turning off "real" sports fans like possible converts from boxing and other "serious" sports.
We won't know until the time comes.
