I can imagine your outrage when books went from being made out of sheepskin to being made out of cotton fibre. You must have gone through the roof when books began to be made out of high acid wood pulp.
I'm perfectly fine with the quality of most streamed Netflix movies. The lack of subtitles is the biggest problem and Starz insistence on dubbing movies is really, really annoying. Do I need every movie I watch to be of superior audio/visual quality? Not if it's a TV show or a "watch only once" type of movie.
There are always going to be audio/visual purists who will complain their eyeballs are being burnt out if they have to watch anything than "the best". So what, y'all inhabit a teeny, tiny space on the planet. If you want your outrageously expensive options, that's fine, but most people just want to kick back and veg.
