The movie "Slender Man" is inspired by the fictional character created on the internet in 2009, which became a part of online folklore. While the character itself is not real, the film is loosely connected to a tragic incident in 2014 where two 12-year-old girls in Wisconsin attacked a friend, claiming they were influenced by the Slender Man mythos. This event drew significant media attention and raised discussions about the impact of internet horror stories on young minds, but the movie itself is a work of fiction.

"Slender Man," released in 2018, received largely negative reviews from critics and audiences alike. Many found its execution lacking, citing a weak script and poor character development. The film attempts to explore themes of horror and the impact of internet folklore, particularly surrounding the Slender Man meme, but it was criticized for its handling of sensitive topics, especially considering real-life events. Overall, it may appeal to fans of horror and the Slender Man mythos, but it's generally not considered a strong entry in the genre.

As of October 2023, "Slender Man" is not available on Netflix. The film, released in 2018, can be found on other platforms, so it's a good idea to check services like Amazon Prime Video, Hulu, or rental options like Google Play and Apple iTunes for availability. Streaming libraries change frequently, so consider searching on your preferred service for the most current options.

While opinions on the scariest horror movie vary widely, many consider "The Exorcist" (1973) to be a top contender due to its intense themes, unsettling atmosphere, and the psychological impact it had on audiences. Other notable mentions include "Hereditary" (2018) for its disturbing family dynamics and "The Shining" (1980) for its iconic imagery and tension. "Slender Man" (2018), while based on a popular internet legend, received mixed reviews and didn't achieve the same level of acclaim or fear as these classics.
