I have watched every season since the show began and I always find it boring. Not sure why I keep watching it... I think the first season was the best because they had challenges that didn't involve fighting. Stuff like carrying the coaches on chairs through beach water, or carrying bottles of water up several flights of stairs. While these challenges didn't involve the skills needed for MMA, they gave great insight into the personalities of the fighters. Without the challenges all the fighters are pretty much the same. Unless there's a guy with green hair in the house, I can't keep track of who is who.
The actual fights tend to be the most boring part of the show for me. Its much more interesting when the guys are fighting in the house or there's some kind of personal drama between the people in the house about eating each other's food or stealing clothes, etc. And of course, when the coaches go at it, like Rashad and Rampage did, or the way Ken Shamrock and Tito Ortiz did, the show is at its best.
So I'll keep watching this newest version of the show...but don't expect me to like it
