NXT is where you go in the WWE for actual wrestling. Some of the guys they have coming through are pretty great. I actually used to do local shows about 10 years ago with a girl that's in NXT at the moment. Emma. She was insanely young at the time (about 14-15, if I remember correctly), but she since has gone to train with Lance Storm and now here she is. She's got a goofy-ass gimmick, but it seems to be working for her.
Also, Bray Wyatt (TAFKA Husky Harris) is awesome, as is Adrian Neville (former indie darling, Pac). Well worth checking out.
Oh I'm well acquainted with PAC due to his work in Dragon Gate/PWG and it's funny that NXT is where the actual wrestling is now when it used to be Smackdown years ago before it basically became RAW 2.0. I'm not the biggest fan of the WWE but NXT definitely has a different feel to it than their other shows.
