What do they think not showing blood accomplishes? If somebody is so squeamish that he can't stand the sight of blood why would he watch wrestling? Except for young children, everybody realizes that the matches are predetermined but that's no excuse to not even try to make it look at least somewhat realistic or believable. People know fights in movies are choreographed but they still show blood even in PG movies. That's because they want it to look believable enough that people can at least get interested in it at the time they're watching it. You know it's just a movie, but that's no reason to not make the movie look realistic.
