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.
The theater just projects pirated copies rather than DRM copies
I would laugh so hard if they downloaded a version with chinese subs because they are not good enough to find better versions.
