My crowd was fairly silent - except for your usual laughs an "oooh's an aaah's" every now and then - but gave a pretty big applause at the end, which lends credence I guess to the idea that the silence was due to the intense focus on what they were all watching. Also, pretty much everyone was discussing the movie as we all marched out of the theatre. There was a definite energy when all was said and done. My screening was jam packed too. Not a single seat left unoccupied.
