This is a man who proves every man's worst enemy is himself.
This is a great behind the scenes look at the ugly side of what it takes to be a MMA warrior and stay one. Mark discovers that what brought him to the top is going to chew him up and spit him out unless he makes some serious changes in his life. Addictions to pain killers and too much partying used to give him an edge of not feeling pain. His relationship used to be the crutch that would hold him up till the next fight. Fame and pressure to stay at the top makes everything different and more demanding.
All of a sudden he is very alone at the top and realizes he's just not able to do it by himself, never realizing he's the one making that decision he can't do it so he obviously was fooling himself all along.
He has to decide between being tough and living rough to be the champion or caving in to the demands of his manipulative obsessive girlfriend and taking the easy way out to chumpville with the rest of us mortals.
It was awesome seeing the scenes with Bas Rutten reacting to what he saw happening with Mark. As Mark described it -it's weird when everyone else can see what you are doing wrong except you- and that's exactly the place where he was in this movie because he is in a co-dependent relationship with a negative controlling woman. Their relationship is based on his own loneliness, depression and emotional weakness and fueled by her jealousy and fear. The reason they were together is because both shared the same bad habits and loneliness and an attraction to the escape that the other one offered. Unfortunately, people that meet because they share bad habits, tend to only make it worse on both of them.
