If they are adamant about keeping it three hours, then they need to incorporate more style. Stop opening with 20 minutes of talking because it sets a bad pace. Bring back the cruiserweight belt, give the overlooked talent something to do, and get the crowd hyped from the jump. Even if the crowd isn't interested in the talent at the beginning, flashy moves will always illicit a response. From there you start planting the seeds for what's to come in the evening. Cut to a champ, contender, or authority figure arriving at the arena and have commentary tell you the person's purpose for the evening or speculate as to what they might have say later in the show. Fill the rest of the hour with stories/matches that develop the mid-card singles talent.
Open the second hour with the main heel spoutin' bout what he's gonna do to the face, have the other guy respond from backstage and set the main event for the evening. Don't have'm in the ring talking to each other because then it's like "Well, why don't they just fight now?" Same goes for the stale Talking-from-the-Stage approach. Don't be in the same area 'less you're gonna fight. I don't buy you hate this guy as much as you claim if you are able to be within arm's reach or short strolling distance and fukking conversate for 10 minutes. From there go into a revived hardcore title match. Just pure physical fukkery to follow the quasi-slam poetry performance we witnesses minutes before. Hell, it doesn't even need to be the hardcore division. Just have matches that convey that the beef between two opponents is so strong that it can't be contained within the ring. Have that shyt spill into the backstage area like so many used to do. Work in some comical aspects on occasion and it eleminates the need for the pitiful comedy segments that almost always fail. Fill out the rest of the hour with a tag match with teams not quite in the tag title hunt yet, some backstage talking, and selling of what's to come, and have the IC title players close out.
Open the third with some divas. Lots of kids are probably in bed by this point, so you have a bit more leeway with what they wear/do. I prefer they have NXT-level quality matches and relevance, but if you are only gonna treat them as eye candy, then at least do it right. Have the main tag champs or contenders shine in a match after that, have some backstage segments that wrap up mid-card stories for the night and plants the seeds for what's to come on SD! or next week's Raw. Then end the show with the main event and the ensuing fukkery.
That's obviously not a set formula by any means, but I think a Man of the Hour approach could do a lot of good. You keep certain divisions at certain times and see what the problem is. Fans develop a sense of what's happening when, then you got people debating what hour of talent is the most entertaining. Instead of having 150 throwaway minutes that you yourself don't even care for if your pencil is any indication, you got hourly loyalties being built and you could determine which segments were strongest and why. Switch the positioning of the first two hours on occasion to determine whether it is the hour that is over or the talent and make changes based on what you find.
And finally: stop recapping events within the show, it is taxing on one's patience. The attitude of "I can tune in late because they'll recap 10 times anyway" should strike fear into the E because it means that the product is not Can't Miss. Talk about it, play off it with interviews and occasional commentary references, but only video recap it once in the evening, and if someone missed it, they missed it. It's 2015, they can go look it up online in HD if they missed it or go back on their DVR. Let's use that time to develop people, not remind you of what already established talent did 40 minutes ago.
