1. There are far too many PPV's right now. At times there seems to be a PPV every other week which seems to force creative to give dull finishes to matches in the name of continuing a rivalry. Example: The recent Bryan vs Orton rivalry.
2. Should be a decent story behind most matches. Outside of the big matches there are undeveloped stories in most of the matches on a PPV card. The Divas match for example sells the lack of cohesion in Aj's team just before the match, rather then have an example earlier in the week. The Diva's match was not for the title and could really have happened on any Raw or Smackdown, as proved on the next night. So why should we care? Creative has to put a good story behind it, more then just these ones are on a tv show and these ones aren't. Langston and Axel has sprung up out of nowhere, they thought for the first time very recently and then we have to buy in to their match on a PPV, which again could have happened on any of the recent shows. More on this in a moment. Rybacks challenges haven't gone on for a long time either. This has been done before very successfully with Kurt Angle and this was because Kurt was allowed to build momentum over a number of shows. Ryback was given one or two nights to build his story and then was squashed abruptly.
3. The titles don't matter anymore. This is kind of continuing from the previous point. In the past PPV's could push two wrestlers out without developing the story much, but do it in the name of competing for a title, usually a midcard one. Back then though the midcard titles mattered, wrestlers sold how much they wanted them in promos, champions weren't squashed every week, and the number one contender usually had to win a few matches or done something of note before getting their shot. This doesn't happen anymore so when you're trying to book Curtis Axel vs Big E Langston at a big PPV it's no surprise that the match isn't a highlight and feels like a filler match. The Divas, Tag Team and US titles were all rested at Survivor Series. The match for the WWE title, seemed to be more focused on other issues. The only match that felt like it might be about the title is Cena vs Del Rio and that was a rehash from of the match from Hell in a cell. This is one of the big four PPVs! Perhaps the one good thing to come out of the unification match is the belts will be the focus, it has to happen consistently for them to mean anything in the long run but perhaps this is the start.
4. WWE isn't giving the fans anything special. The reason the OP is calling for blood, violence and sex is because the OP more then likely has come away from the PPV thinking "well nothing much happened there". The WWE can sell matches without blood, sex and violence but it has to have matches with stand out moments. For me there was one OMG moment at Survivor Series, when Roman Reigns speared Rey Mysterio just as Rey seemed to be going through the old 619 routine. It surprised me and it was awesome. But where was it? right at the beginning of the show. The rest of the card had good matches but nothing with a truly stand out moment. All the results were pretty predictable and some of the finishes were flat. If you want to do such a PPV then yes you need blood, sex and violence to sell it. I can't think of too many other OMG moments in any other PPVs, moments that were unpredictable. The last one perhaps was AJ turning on Cena for Ziggler to win at TLC. Not every match needs one but you need a few of them at the PPV and you need at least one of them to happen in your marquee matches.
5. All the great performers are stuck in the early matches. Best performers of the last year? The Shield, Daniel Bryan, CM Punk, Cody Rhodes and Antonio Cesero. Last month or so, throw in the Wyatts, Usos and Goldust. Where on the card are they? At the beginning or in the middle. In tag matches. With little or no time to express themselves. No wonder the event seemed boring. Want John Cena or Randy Orton in the main event and not against each other? Then put one of these guys in the match with them, with the same attention to storyline you've given the Big Show and you might make some magic. Is it no surprise that the match featuring just the abilities of two of the more average performers of the last year feels in need of jazzing up with abit of sex and violence?
