A Useful Ghost: Ratchapoom Boonbunchachoke embraces the absurdity and silliness of his film’s concept, even as it maintains a straight tone. The film tells the story of home appliances being possessed by ghosts, in particular a vacuum cleaner that is possessed by the daughter-in-law of a factory owner. It is a bit overambitious with its ideas, and it becomes a bit too busy as it deals with memory, retribution, state violence, and queer sexuality, among other things. As a result, it’s very entertaining, but the landing is a tad bumpy. As far as performances go, the film interestingly opposes a very deadpan delivery by the principal performers with an almost comic-like exaggerated reaction by some supporting performers. Davika Hoorne plays the sweet ghost, Wisarut Himmarat her loving husband, Apasiri Nitibhon his stern mother. Production designer Rasiguet Sookkarn comes up with a few very interesting sets, and cinematographer Pasit Tandaechanurat’s static camera is instrumental in giving the film its tone.
