Ate you really a "cinephile" if you go to the cinema so infrequently that you're surprised by the ads and trailers? They are extremely predictable, as is the amount of time they will run for. You can just go later, no one is forcing you to sit through a 25 minute "pre-show" if you don't want to.

This is up there with those people that buy food and drinks for their entire family and then complain that watching a film in the cinema is "too expensive". No one is making you do these things guys, they are a symptom of your own stupidity.
