The imminent release of the highly anticipated return to the “Final Destination” series, “Final Destination: Bloodlines,” calls to mind one of the most iconic aspects of the horror genre: a great, memorable and exciting opening. As horror films rely on sustaining tension and terror for most of their runtimes, it is exceedingly important to introduce said tension and terror in a way that hooks the audience with intriguing storytelling and good scares. Whether or not the film holds up after a fantastic opening is a different story, but even overall duds have the potential to at least provide a thrilling intro. In an effort to spotlight more recent and/or overlooked examples, the unforgettable openings of classics such as “Halloween,” “Scream” and “The Exorcist” won’t be listed.
