Naomi/Cameron makes sense in being a pre-show match. The match being aggressive was a smart move, considering the anger that's been building in recent weeks. Naomi gets the win, rightfully so for me, but with the Cameron attack it keeps her strong and the feud going. Good call there.
2 out of 3 falls? I like it in this match rather than in the
match at the real Battleground. Del Rio getting the pin and Sheamus the submission was different, rather than the reverse which would've been more predictable. Del Rio gets the title, hopefully adding prestige, and Sheamus gets a chance to move further up the card. Good title change.
Couldn't care less about this feud honestly. Not crazy about Dolph getting a new valet, although I know WWE is moving towards this. Dolph going over is the right call.
Battle Royal is next. Rollins didn't need the win, and the Ambrose attack is in-keeping of the feud thus far. Sheamus just lost a title so didn't need another one. Cesaro's win makes him look stronger, building to an inevitable Cesaro/Brock match. Two big battle royals this year though, and Cesaro's won them both: this could both be seen as a good thing or a bad thing, and I'm not really sure which.
Typical heel move from Rusev walking out of the match. I'm presuming that you're going to push Swagger, as being the first man to escape the Accolade is a big achievement.
Bray/Jericho, from a booking perspective was perfect. Both men stay strong, furthers the feud, makes the Usos strong. Bit of the shame there's no Usos/Wyatt Family match though.
Paige/AJ match was interesting. Expected a full heel turn from Paige, but you kept this feud going on at a tweener-tweener level. Keen to see how this progresses.
Good promo showing the Authority in a powerful light, and foreshadows the ending.
Don't normally like the "finish reversed" scenario, but I can tolerate it gives the Authority more heat. Lesnar returns at a good time and makes an impact. I'm wondering whether HHH knew about Brock, seeing how he wanted Rollins. If he didn't know, is this the start of a Lesnar face-turn? Regarding the titles being de-unified, I'd rather Brock wins the WWE WHC at Summerslam, then HHH strips him of one due to his part-time schedule. However, if Brock is going to stay permanently, then either way works.
Overall: 7/10. A solid start. Booking was generally great, the matches were of decent length/depth. However, on a PPV, some more promos would've been nice, as essentially there was 6 matches back-to-back, only separated by a brawl after Wyatt/Jericho, and some celebrations. But good going Shazzy.
