With todays movies, you’re right.
W ith a really good movie, and a full theater, there is an electricity and energy in the air. That’s something that no home theater can duplicate.
There’s a kind of social electricity when you know that a crowd shares your emotional outlook, and there aren’t too many snarkers in the audience to ruin it. E.g., it was fun to watch the final fight scene in the Rocky movies in a theater. Plus, the big screen holds your attention - it has a kind of super-reality - that even large-screen TVs cannot match.
Some deliver it better... spielberg has one... the commie bastard.
