When I went to see Pan's Labyrinth for the first time the theater was relatively empty besides my group of friends and these 3 people a few rows back. They talked, giggled, and laughed throughout the entire movie-a few times I looked back there to see one of them them excitedly engaged in telling the other two a story, waving her hands around & whatnot.
Eventually we asked them to shut up but it only worked for a little while. I don't understand why 3 adults would pay to see a movie & just talk the whole way through it? Everyone else that I was with could understand the dialogue even though I had to read the captions but its still annoying to have someone chatting throughout the whole movie. I just used it as an excuse to see it 2 more times after that.
