Nearly 4 decades later, "Treehouse of Horror" remains a big part of the show's legacy, giving audiences a mix of horror, comedy, and pop culture references to look forward to every October.
Over the years, "Treehouse of Horror" has found different ways to put its own spin on horror classics and popular movies. Season 6 gave viewers "The Shinning", the show's parody of Stanley Kubrick's The Shining, while Season 11 brought the '90s slasher genre to Springfield with "I Know What You Diddily-Iddily-Did". More recently, Season 34 took on Stephen King's It with "Treehouse of Horror Presents: Not It", turning the horror classic into a full-length parody.
This season's "Treehouse of Horror XXXVII" continues that tradition with a stop-motion opening inspired by The Nightmare Before Christmas, featuring Bart as Jack Skellington, Marge as Sally, and Homer as the Mayor of Halloween Town.
The franchise continues to find new material to work with. Whether it's taking on a classic horror movie or putting a "Simpsons" spin on a familiar Halloween favorite, the specials give viewers something different while keeping the humor that makes the series recognizable.
The franchise isn't afraid to try something different, even after nearly 4 decades on television. In Season 38, "Treehouse of Horror Presents: The Revengening" steps away from the traditional 3-story format to tell a single continuous slasher story ahead of this year's "Treehouse of Horror XXXVII".
The episode starts with Springfield trying to have a more controlled Halloween through its "Safe-A-Ween" celebration. Meanwhile, Homer Simpson, Professor Frink, Superintendent Chalmers, and Dewey Largo sneak away to an abandoned brewery party. After a night of drinking, they hit a figure wearing a Daft Punk helmet and monk robes. Instead of dealing with what happened, they keep it a secret. A year later, that decision comes back to haunt them when the masked "Daft Monk" killer begins hunting down the people involved.
Even with its darker, TV-14 slasher setup, the episode still uses the characters' personalities to drive the comedy. Things get even more complicated when Marge reveals that she also hit the same figure. The story eventually leads to a town-wide confrontation at Town Hall, where nearly everyone in Springfield — except Lisa — believes they are responsible for the victim's death.
The victim turns out to be Apu, who explains how the townspeople repeatedly injured him and left him behind before he ended up on the Island of Forgotten Garbage with Dr. Nick. But in a final twist, the entire revenge nightmare is revealed to be a dream inside Apu's head. The episode takes a familiar slasher setup and turns it into another example of the show's willingness to take its characters in unexpected directions.

The reason "Treehouse of Horror" keeps coming back each October is that it gives viewers a mix of familiar characters and new horror-inspired stories. Springfield's residents can find themselves facing supernatural threats one year and making terrible decisions the next, but the comedy and personalities that viewers know are still there.
That balance is what helps the specials remain a Halloween tradition. The references change, the stories take different turns, and the show continues to experiment with its format. But viewers can still return to Springfield every October for the mix of spooky stories and "Simpsons" humor that has made "Treehouse of Horror" a lasting part of the show's legacy.
