5. The Visit 

The Visit is one of Shyamalan’s best movies ever, anchored by an all-time Shyamalan twist that transforms a seemingly lighthearted found-footage horror movie about eccentric grandparents into a full-blown nightmare. From the start, the weird old-people behavior, unsettling house rules, and eerie late-night noises make it clear that something is seriously wrong beneath the surface. I would love to once again feel the shock I felt the first time I encountered this movie’s twist: the “grandparents” aren’t grandparents at all, but escaped mental patients who killed the real couple and have been impersonating them the whole time. It’s an absolutely insane twist, but what makes it so good is how Shyamalan keeps you ever so slightly off-balance the entire movie—one minute you’re laughing at their weird quirks, the next you’re questioning if something’s really wrong, and then suddenly, everything turns horrifying in an instant. It’s Shyamalan at his best, flipping the whole movie on its head in a way that’s both shocking and completely brilliant.
