I've always liked the hidden camera segments TNA did, mainly cause it was something unique that WWE didn't do and it was cool. Plus you could've done a neat thing like have a storyline where Dixie/Hogan/whatever is trying to find out who's this "insider" recording shit in secret.LU from what little I've seen is the right way to do a studio wrestling show. NXT also does it right but it's clear that they go wrestling first, tv show second whereas LU is TV first and foremost.
You'd think TNA which has now been a TV first product for 5 years would have figured their shit out but nope.
TNA could've easily been what NXT is today with the talent roster (and potential talent roster) it had but bad booking decisions pretty much destroyed the brand.
I mean how could you blow this lineup of talent:
Sting
Kurt Angle
HULK HOGAN
Christian
The Hardy Boys
The Dudley Boys
You could build an entire promotion around these guys alone and carry it into a real WWE alternative. Then you could elevate the TNA originals using these guys to make the product a more unique brand than WCW/WWE/ECW 2.0.
