Briefly on the scrapping ideas point. The fact is it's a PG show so i think maybe The WWE Creative feel the majority of their audience is kids either they wont remember or don't care that they have dropped ideas as long as there is flashing lights and Cena they are fine.
Lot of idiocy in that statement. Like a lot of foolish people, for some odd reason, you operate under the assumption that PG=Mostly for kids. WWE Creative not only doesn't feel that the majority of their audience is kids, they actually know that they're not. How do they know that? Ratings reports. Every Tuesday, the WWE brass is given detailed reports regarding the numbers Raw drew, the age groups of those viewers, how many total viewers the show averaged, the ratings for every 15 minute segment of the broadcast, etc. Roughly 80% of the WWE audience consists of males at least 18 years of age. Sites like tvbythenumbers.com has all the info, so please actually look some of this stuff up before putting utter nonsense like that in posts.
As to the points some of the points the OP touched on, maybe you're just burned out on wrestling? It can be hard to get excited if you're someone that's pretty much seen everything that's been done and can be done. The ideas of dropping angles & storylines, just letting them go away quietly, or doing the same thing with pushes is nothing new. It's an age old practice in pro wrestling. Sometimes an angle, a push or a feud just doesn't sustain interst or generate the type of interest in fans. For instance, look what's happened to Tensai's push. He wasn't getting over, so the push was halted. WWE was doing something similar with Mason Ryan, but he wasn't getting over and he's practically disappeared. As far as the lower card guys go, a lot of them are typically relegated to Superstars and a few of them to NXT. Why? Maybe WWE doesn't feel they're up to snuff yet, and some of them legitimately aren't. On Raw or SD!, you're usually going to see wrestlers featured on those programs that WWE is sure of and has a lot of faith in.
Right now, a lot of mid-card feuds and the mid-card title scenes have been brought to something of a standstill due to MITB. It continues to be an important and over concept in WWE and the fact that the mid-card titles don't get as much emphasis as the World or WWE Championships...well, that's pretty much how it's supposed to be. Despite the revisionist history some like to spout in regards to the IC title, it was NEVER hyped to be as important as the WWE Championship.
A lot of the problem, in my eyes, doesn't lie as much with the product as it does with internet fans themselves. WWE's not perfect, don't get me wrong. They make mistakes sometimes and sometimes they just outright fuck things up that shouldn't be fucked up. However, internet fans are pretty spoiled as a whole. With the internet ripping away the mystique surrounding wrestling, we have an insider's view, to a solid degree, of the ins & outs of what goes on behind the scenes. We certainly have more access now as to what's what and what goes on than we did 20 years ago. We spend our time surfing wrestling sites for news regarding newly signed or released wrestlers, we look for articles containing spoilers to upcoming feuds, title pushes, who has heat backstage, who is getting pushed further up, spoilers for upcoming wrestling broadcasts, etc. In short, we spend our time finding out as much as we can and, unfortunately, a good number of us net fans bitch about it once we find out. If you're someone that needs to be excited in the sense that you're caught by surprise and hanging on the edge of your seat every minute, then you're going to be disappointed if you're an internet fan.
It's hard to be "excited or surprised" if you're a net fan. Personally, I think the key is to sit back and try to let yourself be entertained. Sure, there are gonna be things that pop up that you're just not into. It'll always be that way in EVERY wrestling company, not just WWE. If you don't like it then, by all means, voice it. Nothin' wrong with that. If you look for something to complain about, you'll find it. If you'll sit back and allow yourself to be a fan; someone that at least tries to let themselves be drawn into a story, captivated by certain personalities and watches the action you'll have a shot at being entertained. At the end of the day, give me interesting wrestlers to care about, solid wrestling actions, storylines that make a modicum of sense, good stories and good promos and I'm happy.
