I figured out it was scripted when i noticed that the guy who gets the crap beaten out of him at the beginning generally makes a wonderful recovery to the pleasure of the audience, and gets the other guy in a great pin.
That was some 6-7 years ago now.
Still fun to watch, the guys are amazing athletes, and fucking huge, i do admire them for what they do. They're still fighting out in the ring, even if it is scripted.
