“Sever” (** out of four) was an unpleasant horror story about a violent patient (Batya Cruz) who escapes an asylum and attempts to enact revenge on an unsuspecting young couple (Maia Kavchak and Garret Caillouet) but they try to decipher who she is and try to turn the tables on her. Competent direction and acting can only do so much with this weak material. Yet another three-piece character story that may have worked better as a play than as a feature film.
