Horror films are designed to scare and disgust viewers with evil characters, plots and events that can range from realistic to completely supernatural. Nobody will ever really understand why people would prefer to put on a horror DVD rather than a nice, relaxing comedy that won't make you jump out of your seat. However, the horror genre has been around for years with classics from Dracula and Frankenstein to modern day versions such as The Hills Have Eyes and The Ring.

A horror DVD is the top choice for many people when it comes to selecting a film which is why this genre has remained a firm favourite amongst movie fans. Maybe it's to laugh at the story lines, pull faces at the disgusting bits or to get adrenalin pumping. One popular theory is that horror films touch on emotions that other films don't. After all what other kind of film can make you bury your head under the pillow, jump at the slightest noise or make you suddenly afraid of the dark?

People know that they can get a thrill from a horror DVD which you can't get from any other type of film. Viewers anticipate an adrenaline rush similar to the kind of felling you get before going on a big ride at an amusement park. That is one of the reasons why this genre of film is so popular - because people know exactly what they're getting and they know exactly what to expect.

People also enjoy the fact that when they are watching a horror DVD they are completely detached from reality. When completely engrossed in a film and sitting on the edge of your seat, it is easy to forget everyday stresses and problems and therefore is a great way to unwind for an hour and a half. This is something you are unlikely to achieve from a light - hearted film as you can probably get distracted very easily.

Perhaps the most obvious reason why horror films are so popular is because people like to watch them at Halloween. At a time when everyone is talking about ghosts, witches and unexplained occurrences, people like to put on a horror DVD and get in the spirit.

There is such a wide variety of horror films available from monster films, gory films, supernatural and slasher films so it is no surprise that there is something out there to appeal to everyone. With such an abundance of films to choose from horror films will probably always be a favourite amongst many people.
