I'll agree with the generic promos and angles that need improving but the characters in WWE are all actually pretty solid. Way more convincing then the cartoon era characters that were coming out in the late 80s/early 90s that made me and so many others tune out of wrestling for a long stretch of time. I am going to list the main wrestlers in the Fed that are getting pushes and if there were better writers/bookers/more freedom to speak on their own, I have no doubt this would be the strongest the WWE roster/character development has looked in years.
John Cena - White rapper / Marine half-loved, half-hated by the audience.
Batista - Pink polo wearing bitter heel. Shit, this is like Lex Luger circa 1987 and Batista rules in this role.
Randy Orton - The Viper gimmick. Has done so much devious shit in the last 2 years that he is really only hampered by the Rated PG product being put out.
Rey Mysterio - Mini-super hero; the little engine that could; ultimate underdog in nearly every match he is in.
CM Punk - Straight Edge Messiah. It's no wonder that people use him as an example as what people like in wrestling since he is largely left to his own devices on promos and angles.
Big Show - Knockout King. Way more interesting than Andre the Giant's son. Bodyguard of weaker tag team partners.
Edge - Rated-R superstar pushed the boundaries of good taste and I'll admit he is stale right now in a Rated PG world. However, his work in E&C / husband of Vivkie shows he has the personality to stand out in general.
Chris Jericho - Still has some of the best delivery for a heel 12 years after his masterful 1998 run. Jericho needs a change in appearance more than anything but his promos and angles in 2008 ruled the world as well as delivering in the ring.
Christian - has absolutely come alive in the ring in the last year but I admit his character needs something dramatic to make him really break out.
The Miz - Real asshole but I think people can relate to knowing someone like this in their everyday life who they wish would get their ass kicked so he would shut the fuck up.
+++++
I am not saying that WWe is perfect and you can tell that the storylines/matches are dying a slow death when half the arena ia quiet for most matches. Still, the WWE's problem doesn't really have anything to do with the roster and more with the sanitized production of the shows. I agree that a large part of the midcard is really, really generic and that has been the difficulty in elevating new talent. Still, the main core group is more believable, more talented than any WWE roster has been in my lifetime.
Really generic guys who need a personality /gimmick change and quick... Jack Swagger (I need to think more about this guy since he is the new world champ), Sheamus, Randy Orton and Cody Rhodes, Ezekiel Jackson, Dolph Ziggler, MVP, Shelton Benjamin, Kane.
Kane and MVP had great gimmicks at one time but don't really have the wrestling chops to see them exceed.
Sheamus as Celtic Warrior isn't really anything to get excited about.
Legacy , Swagger, Jackson, Benjamin and Ziggler remind me of guys who don't really stand out in any way, shape or form. There is absolutley no reason for me to hate or like any of these guys.
I am sort of neutral on guys like John Morrison and Kofi Kingston who have shown flashes of being over but have never really show me anything that says these guys deserved to be pushed, personality or ring-wise.
I am ignoring guys like HHH, Undertaker, HBK etc. because those guys are instititutions and can become stale but can also deliver in compelling storylines.
