Grimm

Buffy the Vampire Slayer combines wry humor with its monster-of-the-week format, presenting a strong lead character battling evil forces. A trendsetter in its own right, it resonates with Grimm's blend of the supernatural and the trials of everyday life.

Supernatural delves into the paranormal and mythological, much like Grimm, with two brothers fighting supernatural creatures. Its long run and dedication to lore make it a staple for fans of urban fantasy and monster-hunting action.

The X-Files, with its exploration of alien conspiracies and unexplained phenomena, hinges on the paranormal investigative thread common to Grimm, and appeals to those who love delving into the unknown.

Teen Wolf offers a blend of high school drama with the supernatural, focusing on werewolves instead of Grimms, but it carries a similar appeal with its youthful energy and mythological creatures.

Sleepy Hollow updates the classic legend into a modern-day supernatural police drama, intersecting history with myth in a way that fans of Grimm's amalgamation of folklore and crime-fighting would admire.
