I'll agree that the idea of it was cool. In practice, though, it accented the fact that wrestling is fake, which is exactly what a professional wrestling organization doesn't want to do. Look, we all know that match results are pre-determined and that performers have to sell for one another. But the product in the ring has to look believable...... or the whole spectacle falls apart.
For instance, take Rey Mysterio beating the superheavyweights. The sight of him pinning the shoulders of Batista to the mat was one of the most visually ridiculous things I've ever seen. And he's a guy!
With Chyna, it was even worse because she lacked the athleticism necessary to make us suspend belief long enough to accept her as a woman who could beat men. Yes, she was strong, but she was also one of the slowest and least agile people I've ever seen in the ring......male or female. One would expect a woman who wrestles a man to have movement and agility superior to his. If she did, we might buy the idea of her being competitive with him. Instead, we had Chyna, who was slow as molasses. Her ring repertoire was equally slow and pathetic looking. It just didn't look real and it was unacceptably obvious that the men were laying down for her.
I could sooner see Beth Phoenix wrestling men than Chyna. That is, if you've got to do it at all.
