The reality is that New Japan has done something the WWE has been able to do and that is establish various factions together in one company and have them feud with each other without the feud taking over. In the past the WWE had let feuds between factions or stables take over the show look no further then "Gang Warfare" in 1997 as an example of how the WWE handles this type of thing. I know that this could be tied back to the differences in wrestling styles between Japan and America, but remember Gedo who books New Japan was inspired by Dusty Rhodes which means New Japan is showing us a style of southern wrestling that has a little Dusty Rhodes in it.
Overall though I like this series enough where I wanted to take a step forward and expand things to a other company as a way to keep this series going of the time being. I will not be focusing on just the good stables or factions either as I will talk about everything I can find from the annals of the WWE which I'm sure will make things very interesting in the long run.
