In a sense, Netflix is making Hollywood compete with itself. If Hollywood doesn't make anything new worth watching, I'll watch something worth the time from years past.
This is why I'm not concerned with the percentage of new "good" films decreasing, if that is in fact what is happening (which is up for debate.) Because we can always watch the very best films of any year, at any time, approximately speaking. If you want to see a recently produced film, regardless of quality, Hollywood will provide that. If you want to see a good film, regardless of when it was made, that's possible too. It's up to the individual to choose. Onus on the chooser.
