Dude, calm down. Nobody ever said anything about throwing out old 35mm movies. You are absurd for even mentioning it. You said HD sucks, Cassidy said that a consensus of cinematographers felt that HD was not as bad as people make it out to be, and in fact very comparable to 35mm quality wise. Fair enough. You don't have to agree with that, I myself was shocked because I always heard the contrary. Of course as technology gets better HD will look better. 35mm has been around for a long time, it is silly to believe that someday some new technology wont replace it, but it is even sillier to say that because it gets replaced that everything ever filmed on 35mm must go too.

A hint of advice, sit back and enjoy the movie with your friends. Like you said it just annoys the crap out of them when you pick it apart like that.
