#4 We don't have good authority figures anymore
For every hero, there must surely be a worthy villain. Stone Cold may have been a highly talented Superstar, but he would not have been as effective without having Vince McMahon to work off. People loved Austin for the way he stood up to the evil tyrant and made the most powerful man in wrestling look like a complete joke.
The storyline was so popular and successful that the company has always tried its best to replicate it. In recent years we've seen CM Punk, John Cena, Daniel Bryan and others all attempt to fulfil that anti-authority figurehead and essentially be the Stone Cold of the new era.
The problem is, in the late 90s we had Vince McMahon. In 2017 we have Triple H and Stephanie. Besides the obvious gulf in raw talent between father and daughter, Stephanie will never be able to fill her dad's shoes.
Whenever Superstars go up against her, they are made to look too weak. They might eventually get their revenge towards the end of the feud, but 90% of the time during the build-up, Stephanie walks away looking to the bigger person.
In the Stone Cold and Vince example, the success was more evenly shared. Vince might occasionally have gotten the upper hand, but it wouldn't be long before Austin gave the crowd something to cheer about.
Fans will soon tire of an authority figure if they are not willing to let the Superstar get the advantage on a regular basis, and this is just something Stephanie seems unable to do.
As far as Triple H is concerned, he doesn't quite work as an authority figure either. He is still a pretty good heel, but because of the respect fans have for him, we find it difficult to boo him on a consistent basis. Also, when he is not being the evil COO on RAW, he is playing the lovable father-figure down on NXT, a complete contradiction in styles.
