The main problem is the fact that most of the executives within the WWE don't recognize it as a wrestling promotion, moreso an entertainment platform. Instead of mainly getting storylines revolving around wrestling we get contrived love affairs, a hit star from a superhero show coming in to help stop a super villain, and a dastardly duo that everyone wants to stop, but won't bring it up unless it pushes an arch forward. The diva's can't get any storylines without them bringing up their superstar boyfriends, or how one is so popular outside of the WWE.
The reason why so many people deem NXT as the WWE's best product is because all of their major storylines revolve around wrestling. Bayley was built up over the past year to finally win the women's title, she earned it. She didn't win it because of mainstream success, or the fact that she just so happened to be dating a bonafide WWE superstar. NXT is good because of how Triple H has wrestling as its forefront. And guess what? It's PG.
The same can be said about ROH, its weekly programming is PG, yet it's still good because it's focused on wrestling.
What I want from a wrestling show is good wrestling, and stories revolving around what's going on within the ring. Oh, and only spending more than two hours watching wrestling for special events. A weekly three hour wrestling show is completely absurd.
