Edit: I agree Netflix has good Originals. But most are from the early days when they favored quality over quantity. It is sad to see that they reversed that. They have much funding power and should give it to great art that really sticks, has ambitions and something to tell, and values my time instead of mediocrity.
But TV today is at least 55 inch and in crisp 4k resolution. A modern TV is good enough for most content.
It is not Netflix that killed the movieplex. They were just the first to utilise the new tools. The movie theater became the steam locomotive.
The issue IMO is so few movies are worth any extra effort to see. Steam a new marvel movie and you can pause half way through when you’re a little bored and do something else.
Going to the movies costs an extra hour for the round-trip to the theater, ~$40 for adult tickets, ~$60 for the kids (2h babysitter or movie tickets), ~$20 for concessions. Whereas watching at home on our 75" TV with homemade popcorn costs a tiny fraction of that, even including electricity and popcorn kernels and the amortized cost of the TV.
As nice as it can be to see a good movie in a theater, it's typically not so much better than watching at home that it's worth an extra hour and more than a hundred dollars.
