This is actually a great example of the effects of preexisting bias on attributions of causation. If you believe "people don't like gay movies," that allows you to blame a movie's failure on its gayness, even though "people don't like bad movies" is a much more well-established proposition. I have a friend who uses Elektra as an example -- plenty of superhero movies have failed, but Elektra is used to show that people won't go to female-carried movies.
