#1 Worst: Audio issues
Impact Wrestling kept advertising the fact that they had a sold-out crowd at United We Stand with standing room only. There is no reason to dispute this claim at all because a WrestleMania crowd is guaranteed to attend all of the festivities over the week.
But the issue with this whole affair is the fact that this did not feel like a sold-out crowd because the audience wasn't mic-ed at all. You could see the audience losing its mind in the stands, but that did not come across and this led to the whole audience experience being severely impacted.
The Fite stream also had a variety of audio issues through its duration and there would be points where nothing was audible at all. I could see many other users complain about the same too.
These are strange production issues, because Impact's TV product is usually top notch.
