Obviously you'd want it to be fuller, especially given the huge gimmick match, but it's not like the building was half empty. Those few sections to the right of the hard cam are the last to be filled and AEW usually does pretty fair with them (whilst WWE, who run bigger arenas, have struggled to fill that side in general.)
For some reason, the mid-south doesn't seem to be a great market for AEW yet. That show in Raleigh is the only other one you can point to where those sections were mostly empty.
