Movie-goers sue theaters for showing ads instead of the movie at the advertised movie start time. They're asking for minimal damages, and are obviously more interested in getting theater chains to change this offensive practice.

Most movie-goers consider trailers before a movie to be a separate issue, an expected and sometimes eagerly anticipated part of the movie-going experience. Not that 20 minutes of trailers isn't also a problem these days (and if you've been to a movie lately, you know this is not an exagguration).
