I agree with you.  TNA has gained a lot of stars in a short amount of time.  What they have done in the last couple of weeks looks much better, but they're going to have to continue to do a good job of managing the stars in order to make it work over time.  They can't go back to the old WCW days where the young guys got shoved back into a corner and only the old guys got a good shot.  They're going to have to continue to push young talent.

I'm willing to give it a few weeks and see where these angles go.    I agree that they can't just bring out the NwO retreads.   I, for one, wince every time I see Scott Hall trying to recreate his old image.
 
In Bischoff's book he talks about during WCW's heyday,  they didn't do anything to bring up the new talent, and kept relying on the older guys.  And what a mistake that was.
 
Hopefully in a few weeks the angles will lead to the older guys in a side role, like Flair behind AJ, providing plenty of entertainment but letting the new guys do the heavy lifting.

"WE WRESTLE"
I remember that catch phrase. I believe they would gain more fans/viewers if they would wrestle instead of whatever that is they do today.
