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 mean unfortunately denuvo has been pretty effective lately. It’s not uncrackable but not a lot of effort is being put into it other than when Empress feels like it.
