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.
For me, the price is killing it (80% of the reason) and bad movies (20%)... two tickets, drinks, popcorn/nachos/candy/something, and we're in the 50eur+ range. Then add the messy audiences, ads, trailer#1, more ads, trailer #2, another ad for some reason, and it's been 20 mintues of technially all ads for something that i paid money for. Then the movie is a total disappoint. I'm not into superheroes nor into pedro pascal, so most of the movies are out before i even buy the ticket and the rest are somehow... just 'bad'. Watching a bad movie at home is ok... you fall asleep, press stop, it doesn't matter... whatching a bad movie at an artsy film festival is also ok.. it was low budget, the ticket was 4 euros, no popcorn, had beer before you enter, so you can fall asleep in the cinema and hope not to snore. But 50 euros and all the ads for a bad movie is just too much.
