This!! Most speakers/soundbars suck, and if you don't have a center channel in your sound system, voices will wash out with the background noise/music since the speaker (as in person speaking) is usually the focus of the shot and mostly audible in the center channel.

There's supposed to be sound engineers on every show/movie to make sure it sounds good but the gap lies between your audio system and the reference systems they use. A good analogy is the infamous Game of Thrones battle that was too dark. They edited that episode on reference grade monitors where you could see what was happening, but the average lower end tv and viewing environment couldn't translate the same black levels and details that the editor's had seen when they worked those scenes (they were also intemtionally edited to look dark and chaotic on the reference grade monitors*, which added to the problem)

That being said I still use cc with a lot of content. I think it would be less prevalent though if it were not for the gaping holes in most audio setups.
