In my angst-riddled teen years, I loved the movie Underworld. But as the sequels came along, there was a problem that my younger and stupider self could not properly articulate. I now know that the problem was that I could not properly identify the franchise's genre.
The first Underworld movie clearly tried to move away from tradition by making their vampire/werewolf movie more sci-fi. Rather than being mystical immortal beings, they gain their immortality and powers from a strange virus.
The second Underworld movie then seemingly abandons this idea with the introduction of Alexander Corvenus, previously thought to be a "ridiculous legend".
The third movie, quite obviously, does not allow for a sci-fi angle because it is set in the distant past where the very concept of science would itself be considered fantasy.
Come the fourth movie and the pendulum had swung back into the decidedly sci-fi genre with the introduction of the genetically modified werewolves.
As it stands I have yet to see the fifth installment in this series of films, but I doubt it contains the key to reconciling this issue.
With all this in mind, my question is: Is the Underworld franchise sci-fi or fantasy?
