#4 Happy Corbin is a heat magnet
When Happy Corbin and Madcap Moss entered, they had the WWE Universe in Manchester in the palm of their hand. Corbin cut a promo that riled them up even further, with even Madcap Moss cutting one of his favorite jokes. They both played their parts perfectly, and you can tell Corbin loves getting under the skin of the fans.
It is refreshing to see that fans universally dislike a particular character. They say any reaction is positive, and Corbin got all of the arena's attention, even if they called him a chicken thanks to Drew McIntyre hyping the crowd to chant it at him.
#3 WWE made full use of Sheamus' fandom for Liverpool FC
For those who may not know, the cities of Manchester and Liverpool do not like each other. It is a historical rivalry between the two cities that goes back generations. So when you have Liverpool supporter Sheamus walking into the AO Arena in Manchester, you know it's going to be fun.
WWE had Manchester City player Kyle Walker appear on screen to challenge Sheamus. He suggested that if the latter lost his upcoming tag team match, he would have to don the shirt of his rival team. Of course, Sheamus lost, and Cesaro made sure he put on the shirt after some resistance from the Celtic Warrior.
It was a fun moment for the WWE Universe in attendance and something you'd only see at a house show.
