Our local movie theatre (suburb of London) does much more than just show the latest blockbusters these days. They have special, low priced, early morning showings for families with kids, late night 18+ showings for movies with lower ratings, autism friendly showings, showings with subtitles, a lot of movies that previously wouldn't be shown much here (Bollywood movies in particular), and of course the 3D movies are helping them, as well as showing live transmissions of operas and plays from various locations around the world and a variety of other events. They've also put in two rows of larger, comfier seats in all their screens, that goes for a higher price, and I expect to see more of that... The theatres too are reinventing themselves.
A lot of those outdoor destinations even seem centered around a movie theater now, which one might predict is also on the decline - though every time I've visited these places, they seem pretty packed. (At least, on weekends.)
