My complaint:
The audio reverberation that you have been adding to TV performances is extremely annoying. It sounds like people are performing in caves. It distorts music, it makes it more difficult to understand people who are talking, it is very distracting from the performance itself. When I am listening to a performance with reverberation I am distracted by thoughts of why are they messing up this great performance with this reverberation
Suggested solution:
Please stop adding reverberation to performances. I have switched channels many times due to my annoyance with reverberation on your shows. I'm sure that there are many in your audience that share my feelings, but it is very hard to find a way of voicing your complaints to NBC.
