Buffy the Vampire Slayer

Buffy the Vampire Slayer is one of the original television series to feature supernatural creatures—long before the likes of vampires and werewolves became popularized in teen fiction. The series stars Sarah Michelle Gellar as the titular protagonist, who is tasked with hunting down the forces of darkness, in addition to vampires.

The X-Files

The X-Files should ring a bell with science fiction fans, as it extensively explored various aspects of paranormal phenomenon. Spanning over 200 episodes, the long-running series can be considered as much a cult classic as it is a pop culture touchstone.

Star Trek: The Next Generation

Before Star Trek hit the big screen, it began as a science fiction show in The Original Series. Debuting over 20 years after the initial release of The Original Series, Star Trek: The Next Generation is one of the more recognizable spin-offs in the interstellar franchise.

Battlestar Galactica

Mixing elements of military science-fiction and post-apocalypticism, Battlestar Galactica chronicles the adventures of a group of fugitive survivors in space as they try to find the refuge known as “Earth”.

The Wire

While this award-winning series hasn’t achieved the level of widespread popularity that the other shows in this list have, it definitely has a strong cult following. Detailing the interactions of law enforcement with various Baltimore institutions, The Wire explores several social issues that are pervasive in modern society.

Veronica Mars

Following the life of full-time student and part-time private investigator Veronica Mars, the series of the same name strays away from the conventions of other teen dramas and explores darker topics, drawing viewers in again and again each week.

Twin Peaks

Aside from being one of the highest rated shows of the '90s, Twin Peaks has developed a strong following and is consistently referenced in popular culture. The series follows FBI special agent Dale Cooper as he tries to unravel the mystery behind a homecoming queen’s murder.
