Where to start: There are two ways to watch the Insidious series: in release order or chronological. Release order is easy, but if you wanted to watch chronologically you’d have to watch Chapter 3 first, then The Last Key, followed by Insidious, concluding with Chapter 2. Either is fine, though watching it chronologically does forfeit some mystery.

6. Evil Dead (1981-Present)

New Line Cinema

This groovy series all stemmed from Sam Raimi’s original 1981 classic The Evil Dead. Since then it has evolved to sequels and tv series and is regarded as a horror staple and pop culture phenomenon. Sometimes straight horror, but often a horror-action-comedy combination, the series follows Ash Williams (Bruce Campbell) as he discovers the Necronomicon and fights (sometimes through time) against hordes of evil Deadites.

Besides Ash’s obvious charm, The Evil Dead and its sequels (especially fan-favorite Army of Darkness) don’t fail to disappoint. From fascinating worldbuilding that ever-expands the Deadverse to the slapstick humor that has come to define the series, Evil Dead is both pretty scary and a lot of fun.

Where to start: These ones are easy, just watch them in order! The Evil Dead, Evil Dead II, and Army of Darkness are Raimi’s original trilogy, followed by the soft-continuation of Evil Dead, which leads to the television series Ash vs Evil Dead. After that, a fifth film, Evil Dead Rises, will be released in 2022, just in time for next Halloween!

7. Paranormal Activity (2007-Present)

Blumhouse Productions

Say what you will about found footage movies, but Paranormal Activity is among the best. Hidden cameras and jump scares in the dark have made this franchise one of the scariest and most profitable among all the horror films you could watch this Halloween. This series is insane, following demons, ghosts, different dimensions, time travel, and witches that won’t stop until you’re dead, or maybe they’ll settle for being possessed.
