Nope still plenty of stuff, well regarded films and classics even, that have yet to be released (or released in not literally broken form properly). We don't even have all the Hughes or Scorsese films yet.
The picture quality on streaming services stinks and the audio quality isn't tops either and you have no chance for extra and commentaries or alternate endings (which in the case of say Salt were pretty radically different, like what seemed to be a full 20 minutes re-shot!).
I believe that streaming movies is a terrible waste. It's clogging up all of our internet bandwidth for zero need and only to deliver a vastly inferior end product on top!
