Roger Ebert poo-poos the idea that piracy is at the root of dropping film revenues and ascribes the phenomenon instead to crappy movies and crappy theaters that charge too much.
2. Ticket prices are too high. People have always made that complaint, but historically the movies have been cheap compared to concerts, major league sports and restaurants. Not so much any longer. No matter what your opinion is about 3D, the charm of paying a hefty surcharge has worn off for the hypothetical family of four.
3. The theater experience. Moviegoers above 30 are weary of noisy fanboys and girls. The annoyance of talkers has been joined by the plague of cell-phone users, whose bright screens are a distraction. Worse, some texting addicts get mad when told they can't use their cell phones. A theater is reportedly opening which will allow and even bless cell phone usage, although that may be an apocryphal story.
4. Refreshment prices. It's an open secret that the actual cost of soft drinks and popcorn is very low. To justify their inflated prices, theaters serve portions that are grotesquely oversized, and no longer offer what used to be a "small popcorn." Today's bucket of popcorn would feed a thoroughbred.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
