I gave it a try, just because I'm... you know... me.
I wasn't a big fan. There's nothing inherently wrong with it, but what I saw was inferior to what I could get watching guys from New Japan (or even RoH, but we wont talk about that).
There is nobody on the forum who'd like to see a resurgence of the NWA more than me. The idea of a wrestling company that returns to the old school style of running things is my wet dream, or at least it would be my wet dream if I were sexually aroused by wrestling promotions.
The problem is, you can't run a promotion based exclusively around in ring product, then hire a bunch of guys who work no better than those in WWE to run it. In Japan (the best place to look for promotion dynamics, since they have so many) the in ring companys like New Japan are able to hold off the sports entertainment and comedy federations (DDT for example) by hiring guys who can work better matches, and giving them more time to apply their art.
Right now the NWA seems to be hiring guys who are interchangeable from WWE development talent, and then making them wrestle shot matches with one anther, interspersed with the occasional bad promo. This leads to a show that's not inherently bad, but gives nobody other than a xenophobic American who hates the bullshit of the WWE and the over the top nature of Ring of Honor, any reason to watch it.
If the NWA wants to have any level of success without selling out the legacy, they their either going to have to drastically improve their in ring talent, or start trying to run the shows as a legit sport, and restore some of the merits of kayfabe.
