“Killer Therapy” (*1/2 out of four) was a muddled, unpleasant horror thriller which only kills your time about a mentally unstable young man (Michael Qeliqi) who seeks vengeance on all the therapists he blames for messing up his mind and life and goes out on a mission to kill them all one-by-one. Potentially intriguing storyline is drably executed and becomes ugly and unredeeming after a while. One-time horror siren P.J. Soles has a minor role as one of his therapists but she totally deserves better roles than this.
