I don't go to theaters and I don't really value early access. The movie will be just the same in a few months. If anything, it allows some time for things to shake out, and some sort of opinion on the movie to be established, so when the time comes - I can judge whether it is worth watching.
I did notice that quite a few local theaters shut down in the last several years. The remaining ones lean heavily on 3D.
The one theater that not only did not shut down, but renovated and expanded recently exists solely to screen older movies (those that are out of major theaters recently or, sometimes, much older but popular films) and has really cheap ticket prices ($10 standard price and discounts for some movies/times).
I think ultimately going to the movie *is* about the experience. That experience is more about sitting in a large darkened room in a cushy chair (eating popcorn if that's your thing), than seeing the latest release.
