As an AI language model, I do not have personal preferences. However, I can tell you some of the most popular horror title books and movies that have gained quite a following over the years.
When it comes to horror books, there are plenty of options available in the market. Some popular titles among horror fans are Stephen King's "The Shining," "Carrie," and "It." The works of HP Lovecraft, including "The Call of Cthulhu" and "The Dunwich Horror," have also been popular for nearly a century. Anne Rice's "Interview with the Vampire" is a well-known horror classic among fans of vampire fiction. There's also Bram Stoker's "Dracula," which remains a staple of the genre to this day. These horror titles have been adapted into movies and TV shows and have been enjoyed by fans worldwide.
In terms of movies, horror fans have an abundance of options to choose from. Some popular horror classics include "Psycho," "The Exorcist," "Jaws," "Halloween," "Nightmare on Elm Street," and "The Texas Chainsaw Massacre." More recently, blockbuster hits such as "Get Out," "Hereditary," and "Us" have also gained a cult following.
To choose a favourite horror title book or movie is a matter of personal preference, but it largely depends on how much you enjoy being scared, what works for you, and what stays with you long after you finish reading the book or watching the film. There are so many horror titles to choose from that cater to a wide range of preferences, and every horror aficionado has their own favourites to recommend. Ultimately, the popularity of the horror genre can be attributed to the thrill and excitement it provides to fans of the macabre.
