I dislike patrons who have watched the movie, narrating the whole movie to their friends, colleagues, spouses or whomever it is that they came with, for the 2nd viewing. They narrate scenes that has yet to take place in the movie! I still remember the movie was [Iron Man] and there was this whole bunch of school kids, kept narrating the whole plot and how Tony Stark will transform into his alter-ego, even before the movie starts!
