Starts off as a horror-thriller with a pretty simple concept, yet the delivery of it is still kept fresh and enigmatic, but at some point becomes this incredibly profound postmodernist piece on the nature of aging. It would be enough to just focus on the physical aspects of it, which would be fitting for the body-horror vibe this movie is going for, but Old is taking a deeper look at the mental growth, our acceptance of our own mortality, our relationship with the past and particularly our childhood. Shyamalan, as always, manages to find this island of beauty in the sea of horror, making the best moments of the film shine brighter than many peak scenes from his overall better movies. I would have to admit, this is probably one of Shyamalan's weakest works in his entire filmography, but the few magnificent scenes in it are some of the most remarkable achievements of his entire career.
