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 only shortcoming now really is if you want to view with several people and socialize after, it may be difficult for someone to accommodate a large party with good viewing in their home without a theater setup. And of course audio, audio is where theaters can still stand out. It’s a pain in the ass for most homes to setup a good sound system, you really often do want a dedicated theater area which most aren’t going to have. A soundbar helps. You can Jerry rig some surround speakers into any space but it’s often a pain. So that’s really the last barrier: cheap low latency sound that can beat a theater.
For me comfort trumps the slightly degraded sound. Plus some baby crying or random person chatting during the movie can break that as well.
