I've only just caught up with the last few months, but I have a few positive things to say and one concern.
Positive:
1) Corey Graves is the next Jesse Ventura. He is a heel, but appreciates when faces do something good. Colour commentators have spent years trying to be the next Bobby Heenan, but Ventura is far more in keeping with a modern product where its not all good guys and bad guys.
2) Asuka is my favourite current wrestler, possibly my favourite wrestler since I came back to wrestling 8 (eight) years ago.
3) American Alpha are excellent, but in the hour and a half it took me to read through the last 500 posts in this thread, I read lots of comparisons to WGTT. To me, they're a lot more like the Steiners in that they actually have a personality, and I think that's what they are going with with the ring attire.
4) The British audience did me proud by singing their own (mostly football) chants.
5) When I first started watching NXT a year ago (but caught up from September 2014) the people everyone thought were shit were Bull Dempsey, Mojo Rawley, Baron Corbin and Carmella. Of those, only Mojo hasn't improved dramatically (RIP Bull), but more to the point all of them are a lot more over, NXT truly does build people better than anyone else. Apart from Solomon Crowe, who was absolutely shit, has a single wrestler totally fallen on their arse in NXT?
Which brings me on to my concern. NXT is growing so fast and bringing all these guys in that the roster is going to start to strain soon. You can move people up, but the days when you could rely on your average midcarders moving on are gone. Ziggler and Barrett could have gone to TNA three or four years ago but now its so beneath the WWE, why would they? With that in mind, once everyone moves up they will go into the endless midcard shuffle. Eventually that's going to get full and then there'll be too many people on NXT. Obviously NXT will use their good people, so the actual developmental talent won't have a spot. I don't think it's long before NXT goes an extra half an hour or something.
