I just wish Netflix would fix the audio. It gets hinkey approximately in the second season. Very faint, and -- worse -- out of balance. Particularly noticeable on headphones.
It's been that way for months. Which is why I'm to the point of making public comments about such. The Netflix "report a problem" feature, in my experience, never causes problems such as these to be fixed.
Worst case, they should ping the owners and request a corrected copy. Although... such production companies probably die back, technically, after the products (DVD, BluRay, stream, etc.) ship (as a wild guess).
P.S. In another case, I actually managed to communicate the problem directly to the content's original author. Still waiting to see whether that produces a fix (video and audio out of sync, sometimes over a second so).
