I wouldn't mind the ads/theater promos before a movie if they would just
vary them from time to time. I've seen that fucking Charlie Sheen/Jon Cryer National Amusements public service ad ("
No voiceover announcers!") so many times over the past - what, two years? - that I can pretty much recite all of the dialogue from memory verbatim.

Anyone who sees more than two movies per month in a theater will know what I'm talking about here. At least recently the ads seem to be starting
before the movie's scheduled run time in most cases, so the trailers start on-schedule.
