In spite of occasional cheesy digital effects and cheap 2010s production values, tight writing and a well executed concept make Haunter a surprisingly effective atmospheric horror film. Without the need for elaborate makeup or onscreen violence and gore, Haunter presents a terrifying villain, who threatens a plucky protagonist determined to break a cycle of helpless victimization. Although the movie's CGI manifests as a hallmark of low budget cinema, it is not heavily relied upon to advance the plot; the bulk of the film is simply shot within the confines of a basic set, and the narrative is well constructed to function effectively within the movie's budgetary limitations.
