I agree with everything but the eating part. I've recently switched to peppermints. They're like my crack because I always carry around 30 in my pocket. Plus it's cheaper than the old, burnt, tasteless $8 popcorn. The only problem is the noisy wrapper...especially in a silent movie.
I probably would have killed the person who dared do that in EWS. Now there's a movie that needs to be seen in Europe without an American audience! (alongside every other Kubrick film mostly. I did see 2001 here and that had people enraptured, but you simply don't mess with The Master's work.)
