I attended the 11 PM show, which was not cancelled, and when I walked by after Fallout and Galkn, they were running the 12:30 show, so it seems like an anomaly.
That said, they were PACKING people in as a result. The attendants chewed out a person sitting behind me who wasn't thigh to thigh with the people next to him. It was...less comfortable than I would have liked.
