'Possum (2018)' is a psychological thriller laden with symbolism and metaphor, both of which aren't fully fathomable until the credits have rolled. Once they have, however, the piece's previously enigmatic images and implications become much more impactful. In fact, they become downright disturbing. This is the true strength of the bizarre little tale: its retrospective horror. Of course, it has in-the-moment merit, too. This includes, but isn't limited to, a fantastic lead performance from Harris, a creepily ethereal score and some successful surrealist imagery. The spidery puppet that stalks the protagonist is rather alarming, especially when it decides to move. It's not so much a 'creature' as a reflection of both the lead's long-buried trauma and film's true meaning, which collate in a truly harrowing final scene. Obviously, the flick isn't perfect. It's pretty slow and, even, repetitive, especially as it moves into its second act. It also asks quite a lot of its audience, in the sense that it requires total engagement in order for its payoff to really stick. I can see why some haven't connected with it. However, its atmosphere and general intrigue are more than enough for me. When all is said and done, it forms a cohesive and actually quite (unconventionally) scary experience. It's not a nice film, but it's undeniably an affecting one. 7/10
