Clover suggests that the horror research is problematic for a few reasons. Statistical surveys are often sponsored by major studios and don't account for many independently produced horror films. Additionally, some horror films don't get a theatrical release and instead rely on videocassette rentals, an audience that is hidden from research. Rental data from a few outlets also showed that horror films were predominantly rented by adolescent males. Overall, Clover indicates that the typical horror audience breakdown consists mainly of young men, with varying proportions depending on the subgenre.
