I have two requests.
First, stop talking during movies and shows. Just stop.
I even heard a running commentary through a live performance last week that would not be quelled by any number of polite or impolite requests (in that order) to keep quiet. Specifically, I was made acutely aware of how cute the girls behind me found the “tall black guy in the white hat.”
My theory is that home theater systems have gotten so good it’s become impossible to distinguish live theatrical events from images on a plasma screen. Here’s a tip: look around you. If you see people you do not recognize, you are in public, and should keep quiet.
Second, if you go to see a French film that has perfectly reasonable English subtitles (standard placement at the bottom of the screen, prominent lettering, decent translation of the French, et cetera), resist the urge to ask your French-speaking friend, “What’d they just say?” throughout the movie.
If you neither understand French nor know how to read, you have made an inappropriate movie selection. I understand there are several movies out right now that feature marijuana as a major plot point. Perhaps one of those would be more to your liking.
