It is very difficult for some people to be able to understand clearly voices that are muddled from off axis audio recording. It's a real condition. I have hard time hearing voices in a crowded room from people across the table from me. We spend time worrying about the aria tags in our mark up, but we just assume that everyone has the same hearing abilities? I get that most people probably don't think about this when they don't have a hearing condition, but to be dismissive about it is an entirely different level of egregiousness.
Could my initial criticism have been provided with an entirely different tact, absolutely. But after the mental exhaustion that video was, that was all the energy I could afford at the time.
