It was quiet through most of the film, which had, I think, more to do with the audience paying attention and not wanting to miss any details by extraneous reactions. There were some gasps when actual cheating was demonstrated. There wasn't much in the presentation I hadn't already heard about, but the biggest punch in the gut for me was seeing just HOW MUCH coordinated cheating was going on. It was massive. One round of cheering at the end when Dennis Praeger, who had earlier said he was agnostic about all of the allegations, angrily pounded the arm of his chair and said something to the effect of, "I'm convinced! I'm going to fight the left with every fiber of my being!" Big round of cheers and applause for that. Then the chants of "USA, USA" and "Let's go, Brandon" got started. Ordinarily this would have been annoying, but here it seemed to fit. And it was the very end of the movie, so no harm done. Afterwards, there were a few local pols out in the lobby that folks were talking to. And there didn't seem to be any presence of leftie baddies on the scene, which was a relief as I live in a Dominion blue state.
