What film genre features both parody and pornography related to vampires?

The film genre that features both parody and pornography related to vampires is indeed classified under vampire film genres. This category encompasses various films that explore the vampire mythos in diverse and sometimes humorous ways, blending elements of comedy, satire, and adult themes.

Vampire films often lend themselves to parody because they have well-established tropes and conventional narratives that can be exaggerated for comedic effect. For instance, films like "What We Do in the Shadows" create humorous scenarios that play off the traditional vampire lore while also incorporating suggestive adult themes and imagery. This blend allows filmmakers to explore both the campy and erotic aspects of vampire mythology.

The other genres listed—horror, documentary, and action—do not inherently combine parody and pornography in the same way that vampire film genres do. Horror films may handle the vampire theme seriously or focus on suspense, documentaries aim for factual representation, and action films prioritize thrills and physical confrontation, generally lacking in the parody and sexuality found within the vampire genre.
