Previews can be annoying but....

[SteveDallas]

Yeah well, some people need a live. I personally like previews, but I can't stand commercials for non-movie products. (I realize this position is somewhat self-contradictory, but "coming attractions" are a tradition.)

Another movie pet peeve is that the showing of all those ads and trivia questions and such requires them to put the lights down, making it harder to find a seat or to find the people you went to the movie with if you go in separately for some reason. I'd prefer to have the lights up until they roll the previews.
