There's not one single aspect of the production that could have been done better, IMO:
1.) Not hitting Brock's music as usual after the pin like they do for 99.9% of matches. I'm sure they expected an interesting reaction, but I don't think anyone could have predicted how the crowd actually sounded.
2.) Cole says the streak is over and then the announcers go silent, letting the viewer take in the moment and hear the crowd and Heyman
3.) Heyman coming in the ring and looking shocked, the camera hits him at the right time. Adds realism to it, he looks genuinely surprised.
4.) Finding the perfect crowd reactions face shots. They do it all the time now, but this was one of the first times I actually remember them doing this. They found the perfect crowd reactions.
5.) Keeping it silent all the way to when the 21-1 flashes on the screen so you can hear the gasp of the crowd as it sets in what really just happened.
In the longer version on the Network its great because they keep going back and forth between showing Brock and showing the crowd reactions perfectly, and the announcers dont finally start mumbling shyt until Brock is up the ramp.
