I don't think it's just HN readers; I think most people don't mind a few trailers, but the last movie I saw had half an hour of them before a 90-minute movie, which seemed a bit over the top to all of us given that we'd paid quite a bit to see it (ie. it's quite different to free-to-air TV). None of the others I was with are HN readers, but we were all pretty sick of it after that. Probably didn't help that they were all for totally inane movies that we had no intention of seeing - and that "THIS YEAR"/"THIS SUMMER" voice-over really started to grate on me after a while.
