John Carpenter set the bar high by naming his slasher Halloween. Luckily, it’s a film that millions of people want to revisit each and every October. This simple yet aggressively suspenseful tale of a plucky babysitter and a masked murderer has been ripped off and remade more times than one can count, but very few films come close to approaching its devious yet classy style of scariness. The ambiguity of resident boogeyman Michael Myers is part of what makes the original Halloween so damn creepy, and it’s Carpenter’s nerve-jangling musical score that amplifies the suspense to almost unbearable levels.
