From the article:
When we went to our seats, the wait staff let us know that despite the fact that the previews were playing, we wouldn’t know until the movie actually started whether we could see the film or not. If it didn’t work, the screen would just turn black. Luckily, the film went through without a hitch.
I’m not too sure how many independents will be able to afford dumping a quarter of a million to replace all their projector screens
Don’t worry, thanks to this amazing thing called capitalism a big chain will happily buy out those struggling independents at a fraction of their actual worth.
