I think there is another factor to this. Hollywood has fallen off a cliff of late. In my subjective opinion, this started around the mid 2000's and the last decade has been the worst decade for movies in at least 50 years. Look at any top 10 lists for the last decade and the best movies don't hold a candle to what the 90's had to offer. I'll go out on a limb and say none will make it to the National Film Registry for historical preservation.
There's hardly a movie I've managed to watch all the way through, and yet I regularly find myself discovering new gems from the past and getting completely engrossed with them. If anyone else concurs or has some explanations, I would be delighted to hear.
