This is more of a WWE question, but in a lot of ways it could apply to TNA and the indy promotions as well.
Why does the IWC care so much about whether or not one guy is more talented in the ring than someone else? And in what way does that somehow make the show more entertaining?
WWE has a specific set of moves they allow every performer to use, and outside of the occasional surprise, this is all we see of them in the ring. It makes absolutely no difference whether that's all they've been trained to know or not. Even I've been critical of wrestling ability from time to time, but it's usually in the case of someone like The Great Khali or Eva Marie, who simply put, can't move in the ring AT ALL. Even a 3 year old fan in a Cena shirt could see they don't know what they're doing, and only then does it affect the show. Otherwise, it doesn't matter.
I've also noticed that most of the best wrestlers in the current WWE locker room are also the worst entertainers in the company. Natalya was trained in the Hart dungeon, but has a nonexistent character, terrible acting, and the personality of a cardboard box. Antonio Cesaro is a beast in the ring, but I cringe every time the guy opens his mouth to talk...or in some cases, yodel. I don't care about his 5 different languages, being very European, or even a real American. Tyson Kidd, Jack Swagger, Seth Rollins, etc. etc. - all superb in the ring, but as stale as leftover bread where it actually counts.
WWE is sports entertainment company, and they are all examples of terrible sports entertainers. The casual fans usually don't care about how good or bad someone legitimately is, so why should we?
