A teacher in Chicago is suing Loews Cineplex for showing advertisements before movies [Yahoo! News].

...the theater circuit's policy of playing pre-film product commercials amounts to a deceptive business practice because the ads begin at the time advertised as the start of a feature movie.

I wholly agree with this point of view. However, I actually do enjoy watching movie trailers because I like to know what movies are coming out. It is interesting to note, however, that the name "trailer" comes from when advertisements came after the movie. In those days credits came before the movie and advertisements came after. It's funny how that has been turned around. Thanks, Dave, for the link. 10:03:15 AM
