Vampires, werewolves, witches and other supernatural creatures dominate TV today. Numerous TV series explore the possibility of a world inhabited by these mythical creatures and what it means to be a human. Syfy’s “Van Helsing,” a show that is inspired by the popular 2004 movie starring Hugh Jackman and Kate Beckinsale, explores just that and more.

Starring “True Blood” actress Kelly Overton as vampire hunter and killer, Vanessa Helsing, the series’ cast assured TVLine that this is a different show from the existing ones on TV. What makes “Van Helsing” so different? Below are three things that might coax viewers to watch the series premiere on Syfy:

1. There Are Two Types Of Vampires

Generally, in vampire-centered TV shows, there are only one kind of blood suckers. However, in the world of “Van Helsing,” there are two distinct categories.

The first category of these fanged creatures are the ancients – vampires that have been around for a long time and have found a way to adapt to humanity. The second type of vampires are the ferals – blood suckers that are wild since they have fed more on animal blood than human blood in order to survive. This has resulted in ferals developing more animalistic features than the ancients.

2. Several Major Environmental Problems Allowed Vampires To Surface

“There are major environmental problems, which trigger huge catastrophes,” actress Rukiya Bernard explained to the publication. These environmental calamities, such as a volcanic eruption, permitted vampires to crawl to the surface.

3. Only One Person Can Stop Them

According to the official synopsis of “Van Helsing” Season 1, Vanessa Helsing comes from a long time of warriors who have hunted and killed vampires. She leads mankind in a war against the fanged creatures who have emerged as the dominant species in the post-apocalyptic world. Interestingly, Vanessa wakes up from a five-year coma and has no idea where her daughter is.

“Van Helsing” also stars Jonathan Scarfe, Christopher Heyerdahl, Paul Johansson, David Cubbit, Vincent Gale and Tim Guinee. Season 1, episode 1 and episode 2 air together on Friday, Sept. 23, at 10 p.m. EST on Syfy.
