I thought for a hot minute that this would join The Village and The Sixth Sense as my favorite Shyamalans, before the last 15 minutes crash-land hard. Nonsensical stuff often accompany many of his works, but Old is the kind of genre film that really, really doesn't need a relatively grounded, plothole-widening twist, which is even more egregious in how much it's extended, underlined, and explained during the home stretch. Fine, retain that director's insert for the auteurists (and that camera shot is delicious enough), but if we must have twist keep it quick and brief please.
Otherwise, the high-concept pulpiness of this scenario helps smooth over some of Shyamalan's inherent flaws (eg. dialogue that feels like it's translated from another language back to English), and he in turn gives maybe his most animated, best directorial effort ever. Every choice of odd angles and off-kilter camerawork here is so fitting, propulsive, and appropriately disorienting, always striving to unmoor us in the nightmarish slurs of slipping time and clashing mindsets the same as these characters. That I came out of the film surprised by this being PG-13, when in the moment it feels so grisly, is indicative of Shyamalan's suggestiveness of suspense and the horrific and at full power. The director even manages to locate the affecting undercurrent of this premise potently, with the conversation on beach at night as good a resonating emotional scene as he's ever done. 7/10
