But I think it's more than that.
First, there is very little I'm interested in seeing in a theater. It's not even my disgust at Hollywood's politics. Every big new release seems to be derived from a comic book, or, as you point out, a retread. I know this isn't exactly a fresh take on a new movie, but it's relevant to the discussion... was there really any need to remake True Grit?
Second, it's the expense. Not just the ticket price. Popcorn and a drink? Junior Mints? It's worse than theme park pricing.
Finally, it's the behavior of the movie-going public. Cell phones, people carrying on conversations at full voice, that sort of thing. Somewhere we as a society lost a sense of plain old common courtesy, the virtue of respecting others.
I'm trying to think of the last time I ventured to a movie theater, and I think it was to watch Zero Dark Thirty. It's been that long, and I don't miss it.
Of course, maybe things have changed since my last visit to a movie theater. Someone will have to advise me of that.
The Coen Brothers version was both a better movie and more faithful to the book.
