I think a great producer is one who comes up with a style and format which produces consistently good results. Exactly what it is that makes some of those results great, as opposed to merely good, is more subjective and difficult to define.
If sweat is one of the things that does it for you, then obviously the temperature and humidity inside the studio when the match is filmed is an important factor, which may or may not have been under the control of the producer.
Another factor, which even the greatest and wisest student of human nature could never predict, is exactly what kind of chemistry will develop between two females in a situation as physically and emotionally intimate as a fight or wrestling match.
Why did the gorgeous Karen Collins, normally, as Ofecteau says, a pretty lethargic performer, suddenly spark into life and have a real go at Rosy Rocket during their Academy soap match? Why, when Rosy got on top and school-girl-pinned her, did Karen whisper - so quietly that even with the volume on my speakers turned up full I could barely make it out - "I give in."?
That whispered submission was for Rosy's ears only, something real and personal between the two of them that not even Bruce, for all his years of experience, could have predicted in advance. I'm sure he knew that Rosy would beat Karen, but that it would happen like that? Not a chance.
Afterwards, the ritual body-slamming of the loser by the winner and the strap-on sex we knew we were going to see at the end of a soap match took on a whole new level of significance. Rosy "owned" Karen for real, and Soap 46, for me at least, is a great video.
