“Choke” (*1/2 out of four) was an incoherent psychological melodrama about the overlapping realities and intersection of the lives of a devoted psychologist (Lisa London), a brutal serial killer (Shane Ryan), and an astute young girl (Sarah Brine) when the lines between reality and fiction and good and bad appear to blur. Disheveled and cerebral story might make as much sense if you watched it backwards but film is so mean-spirited and unpleasant it’s not worth the bother. Unsatisfying and abrupt ending is a further nail in the coffin.
