Another fan expressed their satisfaction with the unexpected quality, saying, Suddenly, out of nowhere...? They uploaded a B-side performance video, so I clicked without expectations, and my knees buckled.

This showcases fans' positive evaluation of the agency's changed capabilities, coupled with humorous questioning.
