I don't think the comparison of movie theater to home theater is relevant. Who has the space? And like gofar says, it's been around for some time and is affordable to most people. Streaming maybe the mode of delivery now. But the monopoly of providers may hit a wall of consumer revolt like cable provides did. I get along pretty well with free streaming. I don't have to just have what ever is blockbuster new at any given moment.
But if you want a real theater experience, unless your wealthy and can build your own theater. Go to the cinema.
