#3 The Las Vegas crowd was terrible
This one isn't really a moment, but it was one of the reasons why there were so many horrible moments throughout the show. The crowd cheered louder for a beach ball than they did for any stars on the show and made it so that the end to the Asuka v Nia Jax flat seemed flat, the Rousey contract signing didn't even generate the reaction that any other crowd would have cheered for.
There was also a point where the crowd decided to start chanting about Rusev Day rather than the action that was going on right in front of them.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
It's always hit and miss with live crowds but WWE tried their best to ensure that there were enough parts for the audience to be able to make noise on but it seems that this crowd was dead for most parts of the show and made it seem as though this was just another episode of Monday Night Raw.
