Today marks the 20th anniversary of the premiere of “Buffy the Vampire Slayer” and the series finale of “The Vampire Diaries,” making it officially Vampire TV Day.

12. “The Gates” (2010) This short-lived ABC drama centers on a mysterious gated enclave that is home to a wide variety of supernatural beings, vampires among them

11. “The Strain” (2014-2017) The vampire pandemic that brings New York City and eventually the entire globe to the verge of destruction reads more like a zombie narrative.

10. “Van Helsing” (2016) The new Syfy thriller introduces novel elements to the vampire mythos, such as the possibility of a cure for the condition.

9. “The Originals” (2013-present) The Originals” is right up your alley, since it plunges headfirst into a family drama steeped in the rich backstory of its characters right from the start.

8. “Preacher” (2016-present) Cassidy is both very charming and incredibly brutal, and this is largely down to the efforts of Evan Goldberg, Seth Rogan, and Sam Catlin.

7. “Being Human” UK/US (2008-2013, 2011-2014) Strange things happen when a vampire, a werewolf, and a ghost all move in together.

6. “Forever Knight” (1992-1996) The fact that the show’s protagonist is named Nick Knight has drawn criticism.

5. “True Blood” (2008-2014) When we witnessed a vampire get killed off in the pilot episode of “True Blood,” we knew we were watching something ridiculous.

4. “The Vampire Diaries” (2009-2017) What could be considered the successor to “Buffy” received a lot of wit and intrigue from showrunners Kevin Williamson and Julie Plec.

3. “Angel” (1999-2004) There were many possible directions that the five-season series “Angel” could have gone in, but at its heart, it was a detective drama that happened to star a vampire (or two).

2. “Dark Shadows” (1966-1971) This 51-year-old gothic soap opera cannot be evaluated using today’s criteria, as it was created at a different age and followed a different production process

1. “Buffy the Vampire Slayer” (1997-2003) The groundbreaking series created by Joss Whedon has been airing for 20 years and has had an impact on viewers that are still being felt today.
