(SPOILERS for both shows below.)
Nakamura's already just another guy on the roster. His match last night was ok but no different than any other Ziggler match on TV. Nakamura gets an amazing entrance pop, especially last night, but after that, the Smackdown crowds aren't that into him. With his mannerisms my guess is he'll be in a comedy role sooner than later, which is a shame.
Corbin and Zayn had a by-the-numbers match that firmly established that neither of them are going anywhere. Corbin was in a place where he might start getting a push but he would need wins for that to happen. Zayn's a jobber to the stars basically and wins don't do him any good.
The women's six man was ok, at least the women try and come up with different spots. The finish didn't seem to really advance anything - if they're trying to push someone closer to Naomi and the title, last night didn't do that at all.
Owens and Styles will always be in the position to blow a show away. Last night wasn't quite at that level, although they did some crazy spots and were on pace to steal the show before an a 'booked to show off how clever' we are finish. Owens still works like a babyface and it keeps him from being a real top heel and I hated that the top rope crusher he hit wasn't a real finish. Still, no one can touch these two for a match full of high spots.
Harper and Rowan wasn't any good, which is strange, Harper's usually one of the better wrestlers on the card. It didn't click, which didn't help with their position on the card. Harper's always close to being over but doesn't seem to get there.
Orton and Mahal was a standard Orton main event. The crowd was generally into it but Orton only gets reactions for the RKO and that DDT off the ropes spot. Once he hit that on the jabronis the finish was obvious. I don't care about Mahal being champion, the bigger question is who is going to work with him to better establish him as a top guy. Otherwise, he'll just be another Jack Swagger as champions go.
The NXT show was better. As much as I don't love the endless high spot style, for that kind of match the UK title match was top drawer. Roode's a great old school worker who's more deliberate selling-based style is a good contrast to all the high flying everyone else is doing. The show ending angle with the DIY split was super.
There really isn't anyone on any of the rosters that I see as becoming a real main event star.
